There are many different ways in which people come to suffer from Ejaculation Disorder, one of which is the application of too much pressure or too firm a grip during manual masturbation. However, there has been studies presented at the Japanese Society for Sexual Medicine regarding the use of the TENGA CUP Series starting with the Hard series, to the Standard series to the Soft series, lowering one’s threshold to ejaculation to the point where their ejaculation disorder is rehabilitated.[1]
A charity project to support the STOP AIDS fund of Japan and raise awareness of general AIDS prevention. By collaborating with 5 Japanese clothing brands, TENGA raised 2.2million yen through sales of limited edition TENGA CUPs for the Red Ribbon.[2]
