ok so, when my penis isnt erect, i can pull the foreskin over the head without much discomfort. but when im erect i cant get it over more then maybe half of the head. and im kind of worried about sex because i dont want my girl to be like shocked that only half my head is showing. is there anyway to get my foreskin to retract over my head without circumsition?
Foreskin is like that but it stretches over time (just takes a little bit of sexual activities, by a little I don't mean once or twice) You can also stretch it yourself. I'd recommend you doing it the shower. Your penis head probably pretty sensitive too. Try to ignore it and do the stretching, or just explain to your girlfriend that it's fine, it's going to stretch and going to retract without any problems in the future.
