Okay so I lost my virginity yesterday, and the guy that I did it with was a friend, and he was having trouble cumming, so we used a condom at first. And we started having sex, and he was having trouble so I suggested a blow job might do it, so I did and that didn't work either. Then we tried another position, this time without a condom. He obviously said he would pull out  when he thought he was gonna cum, but he never felt anything, so then we just stopped and he said it was his fault bla bla bla haha. When he looked back later at the condom, it had cum in it so I didn't understand if it was pre-cum or he just didn't feel it( which is really weird) so now I'm really nervous that he might have cummed inside of me with out him knowing. I don't know what to do, and I don't know if I should be freaking out or not, someone please help me!!!!!
