Traumatic Masturbatory Syndrome 

Trauma inflicted on a partner during sex from pressing too hard, or repetitively thrusting your body into your partner's causing injury.
That weird syndrome is a result of years of masturbation where your thrusts are controlled by hand grip and that makes it harder for you to carry on with the same rhythm and strenght in real act sex. Sufferers usually lack sensitivity in their sexual organs and finally succumb to desensitization.
Also: TMS.

-Widower's Syndrome (Widow's Syndrome in women) is the 'mirror-disease' of Traumatic Masturbatory Syndrome: a condition caused by lack of sex/masturbation that mighy lead to impotence.

Another urnio-genital skin condition is cunnily called Onan's trauma: hardened penis skin that lack sensitivity from way too much 'jerking the gherkin'!
