Am a guy of 25 who can go a gal more dan 4 rounds. But recently I hv started experiencing one kind of change in my body,I cant go a gal up to 2 rounds again. After d first one, my penis will no longer erect even if d gal romance me from nw till tomorrow it cant stand. And dis always got my galfriend upset and she is suspecting me seriously dat am cheating on her while am not. I hv tried explaining it to one medical practitioner who said am ok dat it is a phychological problem maybe fear, anxiety,alcohol, dat notin is wrong wif me. But wat is happening is still happening and my gal threaten to leave me for anoda guy dat am nolonger satisfying her on bed. Some of my friends are advicing me to start taking man power to help bust my libido anytime i wanted to sleep wif her but I wont continue living on drugs to make a woman feel like a woman. Wat of if I marry tomorrow? Pls pals Advice meon wat to do and am seriously confused and insults are welcomed too!
