Hello, I met a girl on vacation. We kissed a lot and she liked biting my lip a little. It was a bit uncomfortable. We got down to sex eventually and had oral sex. I did it to her. Afterwards, when all the adrenaline had calmed down, my bottom lip felt a bit sore so I went to the bathroom and checked my lip. It wasn't bleeding but a bit redder than usual. Should I be worried? It's clear that I came in contact with viable body fluids but does HIV need to pass through a clear, open wound? I only ask because later, I checked her out and found that she attended an HIV rally in Africa but she is European. I know that doesn't mean she has it but now the idea is running through my head
