Traumatic Masturbatory Syndrome
Traumatic Masturbatory Syndrome (TMS) is the habit of masturbating in the prone (face-down) position. It causes severe sexual dysfunction in most males who practice it. A link between face-down masturbation and sexual dysfunction in females is suspected but not currently established.
TMS was first described by Dr. Lawrence I. Sank of the Center for Cognitive Therapy in Bethesda, Maryland in a 1998 article in the Journal of Sex and Marital Therapy.
Males who practice TMS masturbate by rubbing their penises against their bedding, mattress, pillow, their hand, or even the floor. They do it this way because that's how they learned to masturbate as adolescents, or younger. A survey for an Internet site about TMS found that 61 percent of males who masturbate prone have severe sexual dysfunction, with the most common being anorgasmia (also called inorgasmia), which can be a complete inability to reach orgasm in intercourse, or the ability to do so after only a very long time (half hour or more). Half of TMS males have this problem almost every time they have intercourse, and another nine percent have anorgasmia most of the time. Among males who masturbate normally, only four percent have anorgasmia or delayed orgasm even most of the time.
Many TMS males also have erectile dysfunction. A third of them have erection problems at least half the time they have (or attempt) intercourse, while only five percent of males who masturbate normally do. Two-thirds of males who masturbate prone report having erectile dysfunction at least sometimes, while 86 percent of males who masturbate supine claim they rarely or never do. Most males with TMS can only have intercourse in the missionary position (if they can have intercourse at all).
It is believed that TMS does not cause physical damage, since most TMS males are able to be cured of their sexual dysfunction merely by quitting prone masturbation and learning to masturbate on their backs (supine) with their hand, which is the only way more than 90 percent of males masturbate.
A survey done for the same Internet site among women found that those who masturbate prone tend to have orgasm in intercourse less frequently than women who masturbate supine or sitting, but the tendency is not as strong as among males who masturbate prone. More study is needed among both men and women.
