since i started being with women ive always had the same problem. yet because theyve always been one night stands i always assumed that alchoal had sumthig to do with it. for starters i find it very difficult to achieve a full erection while with a woman (doesnt help that most women just assume that that kinda thing just happens). secondly whenever i penetrate a woman i get alot of pain running through my "banjo string" (the piece of spin connecting the foreskin to the back of the head) meaning that i instantly loose my erection thus having to satisfy my partner in other ways leaving me without release and feeling worried. i have no such problem when i masterbate. this is begining to put me off having sex with women and i guess i should probably see a doctor. but its always been this way.
