so i drank a lot of beer last night and got pretty drunk. i met this girl and we ended up having sex but i wasn't able to blow a you know what...i was no longer drunk when we started having sex and it had been a few hours since the last time i had any kind of alcohol. like it felt good and all but i just couldn't get off. was it because of the alcohol in my system still or could i just not get off for some reason? like has this happened to anyone else before?
