About 4 years ago i had sex for the first time. When we were having sex, the condom was still intact and everything. While having sex and switching positions, the condom was still whole, even in the position we were in before he was about to cum. When he was about to cum he pulled out his penis, took off the condom and cum in a corner. (We didnt notice anything wrong with the condom). Later that evening, when i got home and pee i noticed something in the toilet floating around. I think it mightve been a piece of the condom but i am not too sure.
If it was piece of the condom, is it possible i could have contracted a std ? (I didnt know his status or anything)
