If you're masterbating by using pressure against something such
as your mattress, tables,arm of chair PLEASE STOP IT NOW!
This condition is called TMS (Traumatic Masterbation Syndrome)
Its a severe condition where you cannot cum while having
intercourse! espeically men!
With years of humping on something you're in a state of prone
masterbation rather than using the conventional way, normal way
(which is by lying on your back and using your hands), By
masterbating prone the effect is that when you're having sex
the stimulation of the vagina when you're penus is inside will not
be the same pressure as the object your using to cum hence no
feeling! no erection! no ejaculation! because the nerves are
damaged due to years of prone masterbation
Please! there is a cure and you're not alone I honestly admit i
am one of those guys who do it this way and now i am changing to
have a better sex life and cum the right way
