So i went to a party and got drunk and went to my guy-friend's room and we had sex.. twice. the first time we used a condom. so after he came we laid down for a bit then decided to go for round 2. the second time he didn't use one and i noticed AFTER we started again... he didn't cum the 2nd time.. should i be worried?? i'm kinda freaking out... what do y'all think?!
