I ll try to keep this short. Yesterday I had protected sex with a girl I met. She started giving me a hand job, then protected oral, then let to Vaginal intercourse. It was in a position where there was 99% no skin to skin contact. As we switched positions, I noticed sores on her groin region. We stopped, and she left. (short version) I took the condom off and vigorously washed myself. My questions..... What are my chances I contracted something?? And if so when would I know??
