hello,if I had protected oral and vaginal sex where the condom remained in tact, but the woman I was with ended up being on her period, what are the chances I contracted something? It's been maybe 12 hours, and right after sex my penis felt a bit sore and irritated. However, I have felt this kind of slight irritation before after sex...and this is the first time I've had sex in maybe a month.Note- when i pulled out I also noticed a little bit of blood on the condom.
