Hi So I Was Just Recently Tested For Everything And

Hi so I was just recently tested for everything and my results came back normal and I met this guy and we started hanging out and I got a bit drunk and had unprotected sex with him. He said he is clean and everything was good but I'm worried because when I was shaving in the shower I cut myself and still continued to have sex with this guy. I am worried because I'm not sure what it is if it hurts because I cut myself or if it's in grown hair because I do get those a lot but it hurts.
