well i had sex for my first time but i could not cum. i got her off 4 times and for some reason it wasn't happening for me, im not sure what was wrong my penis just felt completely numb. i didn't feel nervous but im guessing that was the problem, it kind of made it worse because my parents were home and we were being really loud. im guessing ill get over this problem after we have sex a few more times. has this happened to anyone else?
