Strap-on dildo

A strap-on dildo (also strap-on, strapon or dildo harness) is a dildo designed to be worn, usually with a harness, during sexual activity.^[1] Harnesses and dildos are made in a wide variety of styles, with variations in how the harness fits the wearer, how the dildo attaches to the harness, as well as various features intended to facilitate stimulation of the wearer or a sexual partner.^[2][3][4]

A strap-on dildo can be used for a wide variety of sexual activities, including vaginal sex, anal sex, oral sex, or solo or mutual masturbation. Sexual lubricant can be used to ease insertion, and strap-on dildos can be used by people of any sexuality or gender.

Harnesses

Harness types

The first part of a strap-on setup is the harness, which connects the dildo to the wearer's body, usually in a position similar to that of a male's genitals. A good harness should be sturdy yet comfortable, and is often designed to provide stimulation for the wearer. Many types of harnesses are available, with different features and drawbacks. Some dildos do not need a harness or are built onto one; for these, please see the sections on dildo types and dildo attachment methods.

Two-strap

A 2-strap harness, in its most basic form, is similar to a g-string. One strap goes around the wearer's waist, like a belt, while the other goes between the wearer's legs and connects to the other strap in the middle at the lower back. While these are simple, many people find them uncomfortable because the strap rubs against the anus and other areas, and they sometimes do not hold the dildo very firmly, causing it to sag, flop, or twist.

Three-strap

Three-strap harnesses have one strap around the wearer's waist, but instead of one strap between the legs, they have two straps, one around each thigh, rejoining the first strap near the front. This design leaves the genitals and anus uncovered, and attaches the dildo more firmly, giving the wearer more control. Not all people find this design comfortable, and sometimes they are difficult to fit properly, and tend to slip.

Corsets and other clothing items

Strap-on harnesses built into various clothing items are available, most often as a corset or other item of lingerie. Some are designed to be worn underneath normal clothing for quick use (if done with the dildo in place, either to give the appearance of a penis or to be able to quickly initiate intercourse, this is sometimes called packing), while others take advantage of the additional strength and sturdiness an item of clothing can provide over a few straps, or just to integrate the strap-on into an erotic outfit.

Body locations

Harnesses are not limited to the crotch, and indeed many types are available for other body parts. A popular one is a thigh harness, which attaches a dildo to the wearer's thigh (or other part of the legs or arms, though this is much less common), allowing for many unique positions, as penetration is no longer limited to what could be done with a penis. Another unusual design attaches a dildo to the chin of the wearer, allowing vaginal penetration while performing anilingus or vice versa. Also, an additional design is a gag-style harness, in which a gag is inserted into the wearer's mouth and a dildo protrudes at the other end.

Upon objects

Harnesses are available to attach dildos to just about any household object, allowing for many creative uses. A dildo could be attached to a chair, bed, or any other item of furniture, and penetrate someone during other activities, with or without a partner. Another item, while not technically a harness, but worth mentioning, is an inflatable ball, usually 9 to 18 inches (250 to 500 mm) diameter, made of sturdy rubber designed to support the weight of one or two people, with an attachment for a dildo on it. This allows many unique positions, such as double penetration for a woman by lying face down on the ball for vaginal penetration while her partner penetrates her anally doggy style, which is much more effective than a solid object due to the "bounce" of the ball. These inflatable balls are also quite popular for solo use.

Harness materials

Harnesses are available in many different materials, and the choice of which to use depends greatly on individual preference.

Synthetic

Nylon webbing and soft foam-like synthetic leather are common, relatively affordable, and very durable. Synthetic harnesses are relatively easy to clean and require relatively little maintenance. Some, such as the Spare Parts harness, are machine-washable.

Leather

Leather is comfortable and adjusts to the wearer's body, but still is strong. Leather is harder to clean and requires more work to maintain than other materials.

Cloth

Cloth is used mostly for clothing harnesses such as corsets and other lingerie, although is occasionally used by extremely inexpensive harnesses, which are often uncomfortable or useless. Construction of lingerie harnesses is similar to most normal items of clothing, although they may use substantially thicker material to give the strength needed to support a dildo firmly.

Plastic

Some harnesses are made with soft plastic, such as flexible vinyl. These are often available in colors besides traditional black, and may be completely transparent (not possible with other materials). They may be less comfortable than other materials, and may be difficult to make fit well, however they are very easy to clean and fairly robust.

Latex, rubber, PVC

Latex harnesses usually cover the entire area, rather than just using straps. They tend to be medium-priced, and have a limited lifespan, especially if used with oil-based lubricants. Latex can require much care, such as special cleaners or shiners to keep it from turning dry and dusty. Latex harnesses may or may not have the dildo(s) molded as part of the harness, and in either case, they tend to be floppy due to the flexibility of the latex. Similar harnesses are also available made of rubber or PVC, and are similar to latex harnesses, although PVC tends to be much less flexible and elastic.

Dildos

Dildo types

The most noticeable feature of any strap-on setup is the dildo used. A wide variety of dildos are available, and while the choices may be limited by the type of harness in use, generally one can choose from several common types. This section discusses the shape and features of the penetrating end of the dildo, not of the entire dildo or how it's attached, which can be found in the section on dildo attachment methods for the double dildo and strapless dildo.

"Standard"

The "standard" dildo has a non-tapered or slightly tapered shaft, and often has an enlarged head, similar to a penis. The shaft may be slightly curved, but if it is strongly curved, it is often classified as a g-spot/prostate dildo as well. This type is by far the most popular, both for vaginal and anal use, although some beginners prefer a probe-type dildo. Depending on the type of harness the dildo is meant for, it may have molded testicles as part of the base, which many people say gives more pleasure and helps keep the dildo from "bottoming out." Standard dildos are the most common by a large margin, and are available in virtually any length and width, material, texture, etc.

Probe

A probe dildo is often highly tapered, and many resemble a cone in overall shape, or may have a narrow diameter its entire length, although ones resembling an elongated butt plug are also common, their defining feature being a bulb in the middle which tapers down again towards the harness before flaring wider. These dildos are often advertised as being for beginners, especially newcomers to pegging, who may find a narrow, tapered dildo easier to start with if they have never had anal penetration before. Many people find that once they are familiar with the activity, the probe dildos are inadequate and unsatisfying, and purchase a standard dildo to use with their harness. Due to this, many kits include both a probe dildo and a standard dildo, so it is not necessary to purchase another.

G-spot and prostate

Dildos designed for g-spot or prostate stimulation often have a sharp upwards curve at the head, or gradual but still strong curvature the entire length. When used in many sexual positions, the curve causes strong pressure against the g-spot in women or the prostate in men. Some men report that strong prostate stimulation is important for an anal orgasm, while others report it as a distraction rather than a help. When using one of these dildos for the first time, care should be taken at first to make sure it's comfortable for the receiver, as the strong bend can be difficult to insert or control. For many positions, such as doggy style, the curved tip should point downwards, as otherwise it points in the wrong direction for either g-spot or prostate stimulation.

Textured

For added stimulation, many dildos for harness use are manufactured with bulbs along their length, or having ripples, bumps, or other shapes on the surface to increase the stimulation given to the receiver. A bulbous dildo causes repeated expansion of the vaginal opening when used for vaginal penetration or of the anus when used for anal penetration, and causes a unique pulsating effect and additional stimulation. Ripples along the length of the dildo increase friction and cause a washboard effect, which some people find increases their pleasure, while others find tend to cause numbness. Individual bumps or a water droplet texture on the shaft also causes extra stimulation, and often avoids the washboard effect of evenly spaced ripples. Some dildos modeled to be realistic penises contain very heavy vein textures on the surface, causing a similar effect.

Vibrating and rotating

Some dildos, especially recent ones, may have rotating beads along the shaft, a wiggling shaft, vibrating ticklers or other clitoral stimulation devices, or other features to give more pleasure to the user. While their effectiveness is a matter of opinion, they are becoming increasingly popular. An inexpensive design is basically a standard rabbit vibrator designed for harness use (often exactly the same toy with a slightly different base), while more expensive dildos are designed from the ground-up for harness use and are usually superior. Rotating beads provide extra stimulation of the vulva and vaginal opening when used for vaginal penetration or stimulation of the anus when used for anal penetration, while the various clitoral stimulation devices are generally intended only for vaginal intercourse. These dildos are often bulky or heavy, and like all other vibrators need a power source (usually batteries in a pack that clips onto the harness or slips into a pocket on it), but can provide additional stimulation for those who desire it.

Double penetration

Double penetration dildos are generally two dildos molded onto a common base, designed for simultaneous vaginal and anal penetration or simultaneous vaginal and vaginal penetration, not to be confused with a man using a strap-on along with his penis for double penetration, which is discussed below. A typical double-penetration dildo has a longer, thicker main shaft for vaginal penetration, and a shorter, thinner, often more curved shaft for anal penetration. Although rare, dildos with the anal shaft being equally as large as the vaginal shaft are available for women who find a larger anal dildo more satisfying. These dildos tend to greatly limit the possible positions they are used in, as the angle has to be right for both vaginal and anal penetration when thrusting, however they can provide a unique experience for couples to try.

Specialty functions

Many specialty dildos are available, such as ones that expand when an attached inflator bulb is squeezed, simulate ejaculation by releasing warm water on demand when a reservoir is compressed, or function as enema nozzles, allowing an enema to be given while using the strap-on for anal intercourse. Inflatable dildos generally expand in girth when inflated (they usually come with a simple hand-squeeze inflator bulb), allowing the dildo to keep expanding during intercourse as the receiver slowly stretches, giving a unique completely filled feeling which is hard to obtain using normal dildos. Ejaculating dildos contain a squeeze bulb or other reservoir, which when filled with hot water beforehand, allows the wearer to "come" into the receiver at the proper moment. Enema nozzle dildos contain tubing connections, and when used for anal penetration (most often with silicone lube, as water soluble lube would quickly break down when combined with an enema) allow the receiver to receive an enema during intercourse. Some BDSM mistresses specialize in offering this service. A relatively new product in this field is dildos with electrodes for erotic electrostimulation, further increasing the range of sensations the receiver can experience.

Penis extensions

Hollow dildos are often sold as penis extensions, but the most common use is for men with erectile dysfunction. The penis is inserted into the hollow inside of the dildo, then the harness is put on, allowing the man to penetrate his partner with the dildo, the thrusting of which is transferred to his penis.

Dildo attachment methods

The principal feature of any strap-on setup is the attachment—the dildo used to penetrate the other partner. While there's a huge array of different dildos available, most are attached to the harness in one of several ways. All methods have tradeoffs, and many couples will have different harnesses depending on which type of dildo they want to use.

Ring and wide base

The most common means of holding the dildo to the harness is to have an opening or ring in the harness through which a wide-based dildo is inserted. Inexpensive harnesses tend to just have a round hole in the fabric or leather, while more expensive ones will use a steel or rubber ring. The advantage of this method is that dildos which fit are widely available and inexpensive, and even many dildos not meant for harness use will work in one of these harnesses, such as most dildos with testicles. The major disadvantage is the dildo is often held loosely (especially on cheap harnesses) and tends to flop downwards, and the dildo often can rotate in the harness, making it difficult or impossible to use g-spot or other shaped dildos.

Vacuum seal

Used primarily by Doc Johnson, Vac-u-lock dildos have a rippled hollow in their base, which fits onto a matching plug on the harness or other toy. Powdered lubricant is used on the plug to facilitate removal. The advantage of this design is the dildo is firmly attached and can not easily rotate, and does not tend to flop downwards or slip like ring harnesses, as well as there being a wide variety of other devices the dildos can be attached to, such as handles and inflatable balls. The disadvantage is the relatively low availability and high cost of compatible attachments. A number of brands have non-compatible clones of the vac-u-lock system, but dildos and accessories for them are virtually unavailable.

Strapless

A recent design is a strapless strap-on, designed to be held in a vagina or anus with an egg-shaped bulb and thus not to require the use of a harness. This differs from a double dildo where both ends are phallic and a harness is required. The Feeldoe is a strapless dildo which was patented by Melissa Mia Kain in 1997. Advantages of this design are that it can be used spontaneously, that it provides deep internal thrusting to both partners, and that the lack of harness makes it more comfortable. Disadvantages are that the eggs do not prevent rotation or droop, leading to a reduced amount of control unless a harness is employed anyway; a requirement for strong muscles; and the practice needed to become familiar with its use. Many strapless strap ons can also be used with a harness when partners want to increase control. Not all harnesses are suitable for strapless strap ons. It is highly recommended that you use a strap on with very adjustable O-ring or a two hole harness.^[5]

Double penetration

A double dildo can be used with or without a harness, although most provide no means of using them with a harness. A double dildo, as its name implies, is a dildo in which both ends are designed for insertion, and often is 18 inches (450 mm) or more long. While special ones meant for use with a harness do exist, a normal double dildo is straight, is rarely at a comfortable angle for intercourse, and jabs into the cervix of a woman using one. However, double dildos can be used for a variety of creative positions for which a harness would be awkward, such as both partners in doggy style positions or sitting facing each other.

One-piece latex

Some harnesses and dildos are made of a single piece of molded latex, with the dildo permanently built into the front. These are often inexpensive, shoddy products, although higher quality ones are available. The advantages are simple use and an appearance some people find erotic, but this is often outweighed by the inability to use a different dildo, the often weak, floppy nature of the dildo, the inability to adjust to a given person for a comfortable fit, and their relatively short lifespan.

Molded straps

Some very cheap "strap-on dildos" have straps or attachments for straps directly molded into the material of the dildo. This design is very flimsy, and is only used on the cheapest products. They are essentially useless for the traditional purpose of a strap-on dildo (one partner penetrating another using a dildo in a position similar to a penis), but can be strapped around chairs and other objects for a variety of other activities.

Methods of stimulation for the wearer

Pleasure for the wearer of the strap-on generally comes from pressure against the genitals, particularly the clitoris, during use and from psychological arousal. Many designs of strap-on have various features to increase the stimulation of the wearer.

Some harnesses intentionally leave the genital area and anus open (either intentionally with an opening in the material or by the design simply not having any straps that would cover it), which allows any toy to be used for the stimulation of the wearer, or even for the wearer to be penetrated while wearing the strap-on. This can often be useful when the partners wish to switch roles during their play, as the strap-on can be put on before hand without interfering or needing to be taken off for play to continue. This type of harness is ill-suited for using toys, however, as the harness would not touch the toys, both preventing them from falling out while thrusting and not providing movement to them from the harness.

External stimulation

Built-in features

Some harnesses and dildos provide raised bumps or other features designed to rub against the clitoris of a female wearer, either attached to the inside of the harness, or on the back of the base of the dildo. Harnesses that work with such dildos have to have an open back, where the base of the dildo presses directly against the woman's body. As high-quality harnesses usually have padding or other means of attaching the dildo to the harness than a simple opening, these features are usually only seen on low-quality, inexpensive dildos. They provide only limited stimulation, and while better than nothing, are usually considered inferior to other types.

Vibrators

Another means of providing stimulation to the wearer is a vibrating egg, "clit blaster", vibrating gel pads or whiskers, or other device mounted on the inside of the strapon. These are almost always intended for use by women, as the external vibrator is rarely positioned well nor provides stimulation to males. These devices provide external stimulation to the clitoris, vulva, and other parts of the vaginal opening, but do not provide any penetrative stimulation or anal stimulation.

Internal stimulation

Double-ended attachments

While a double dildo obviously would provide stimulation to the wearer as well, the standard straight dildo is very poorly suited for harness use. To overcome this, many dildos are available for harness use that have an offset in the middle, with the main attachment and a smaller vaginal attachment for the wearer having a flat vertical section between them. This way, the main attachment is at a good angle and position for thrusting, while its movement is transmitted directly to the vaginal plug and clitoris of the wearer.

Double-ended/sided hands and strap free dildos

The latest technological achievement is totally new kind of strapless strap on. A special example of these are Feeldoe, Sysil, Super Strapless Silicone Dildo, Share, Nexus Maximus and Transfer, which has an egg shaped bulb designed to be inserted into the vagina or anus of the wearer. Due to the shape of the dildo, thrusting on the main dildo translates to lateral movement of the plug, providing great stimulation to the wearer. Additionally, the shape of the plug allows it to be used without a harness in many instances. It can also allow a man to perform a double penetration (actually doing anal while the dildo penetrate the vagina) while being anal-plugged himself, all with only a single toy.

Internal plugs

Many of the "professional" harnesses have one or two plugs (vaginal, anal, or both) on the inside of the harness, to penetrate the wearer. These plugs (may be shaped either like small dildos, the standard butt plug shape, or a combination/hybrid thereof) are usually firmly attached to the harness, and provide stimulation to the wearer as he/she thrusts with the main dildo. Harnesses made for men usually only come with the anal plug, while ones for women come with both plugs, which most women report provides the most pleasure using one.

While a plug can be used in combination with most any harness, just by inserting the plugs before putting on the harness, all the harness tends to do is push the plugs in, and not move them as to provide stimulation when the wearer thrusts. Depending on the type of harness, different ways are used to properly attach plugs to the harness. A common type consists of an opening or rubber ring with a cloth or leather back, similar to what might be used to hold the main dildo to the front of the harness, but positioned over the anus, vagina, or ones for both. A dildo/plug with a wide base is inserted through the ring, then when the harness is put on, the material pulls tight against it, holding it firm. For vac-u-lock harnesses, one or two additional vac-u-lock plugs are mounted on the inside of the harness, allowing any vac-u-lock attachment to be used. Most vac-u-lock harnesses that have the connectors for internal plugs come with two plug-shaped vac-u-lock attachments, a smaller one for anal use and a larger one for vaginal use. Like other types of harnesses, both plugs may be used at once, and often are separately adjustable on the strap to fit the wearer's body.

Sexual positions

A number of positions can be performed using a strap-on dildo. These include:

• Doggy style: Doggy style is popular as it is simple, easy, and allows deep thrusting. The receptive partner kneels down with his or her face against the bed (or other surface), and is penetrated from behind. This position works well for both vaginal and anal penetration, and allows deep, smooth strokes, however it sometimes stimulates the prostate less than other positions during pegging.
• Missionary: The missionary position is also popular, and allows both partners to cuddle, see each other, kiss, or perform other activities during intercourse. When used for anal penetration, a pillow or other object placed under the buttocks of the receiver will elevate the anus to a comfortable position and angle.
• Bent over: Usually used for pegging, the man stands or kneels while leaning forwards, supported by the bed, chair, wall, or other object. Similar to doggy style, he is then penetrated from behind. This position angles the dildo such that it typically strokes firmly across his prostate, and for some men can lead to an anal orgasm much more effectively.

Common uses

Even more than the different types of harnesses and dildos, there are different ways to make use of a strap-on setup. Generally ways of using them can be divided into several broad categories, however there are infinite variations.

• Pegging: Pegging is when a woman uses a strap-on dildo to penetrate her partner anally, usually a man.
• Sex between women: Female, same-sex intercourse is one of the more common uses of strapons. Strap-ons are one means for women to enjoy penetration with their sex partner.
• Erectile dysfunction: Men with erectile dysfunction may use a strap-on to help satisfy their partners, either by using one with a hollow dildo, or by having their penis hang beneath the dildo.
• Double penetration: Some women find simultaneous vaginal and anal penetration to be enjoyable, and aside from using a double-penetration dildo discussed previously, can experience this with a male partner using a strap-on. A harness is selected that allows the man's penis to extend under the dildo of the harness, thereby allowing him to insert both his penis and the dildo into his partner. In a face-to-face position (such as the missionary position) the penis would penetrate the anus and the dildo the vagina; in a position such as doggy style the penis would penetrate the vagina and the dildo the anus.
• Masturbation: Non-traditional harnesses, such as furniture attachments and ride-on balls, can be used for masturbation by both men and women. A ride-on ball can take the position of another person, in that it can be on bottom for most positions that have the person being penetrated on top, and furniture harnesses can be attached to many objects, an example being a bathtub, to penetrate the user doggy-style before or in a bath.
• Transsexual people: Some transsexual people use a strap-on to provide the function of a penis, for example an FTM, as he was not originally born with one. This option may appeal to people who have not undergone surgery, for any one of many reasons. Strap-ons may also be used by MTF transsexuals, who are either genitally post-operative or not using their own phallus.
• Orgasm Denial: Some heterosexual couples use a strap-on to allow penetrative sex while denying the male partner the ability to orgasm.
• Other: Many people, using a strap-on for any of the above purposes, often like to either suck or have a partner suck a strap-on, performing fellatio on it. The reasons given vary, but mostly have to do with power or role reversal.

Almost every position associated with sexual intercourse (or not, in the case of simultaneous penetration) can be performed with a strap-on. Indeed, with other harnesses that allow a dildo to be mounted on inanimate objects, endless new positions can be conceived.

History

Due to the often taboo nature of strap-on activities, information on their history is difficult to find. An 1899 report by Haberlandt documented current and historical use of double-ended dildos in Zanzibar, and is one of the few historical documents of this kind. Female-female dildo usage in ancient China has been documented, but it is not clear if this was double-dildos, strap-on dildos, or just a simple dildo being used by one woman on another. In ancient Greece, dildos were made of stone or padded leather, and some evidence shows aforementioned leather was used to make a harness as well, with olive oil used for anal penetration. A double-penetration dildo was found in ancient France, but its use is lost to time. A 19th-century Chinese painting shows a woman using a dildo strapped to her shoe, showing that creative use of strap-ons was already well under way. Many artifacts from the Upper Paleolithic have been found that appear to be dildos, including a double "baton" with a hole in the middle, theorized to be for a strap to hold it to a wearer. The Kama Sutra includes mention of dildos (darshildo in Hindi) made from a wide variety of materials, and used by hand, with ties (straps), or in a harness. It is likely the history of the strap-on parallels the history of the dildo, and given the age of many discoveries, is a rather long history.
