Yesterday I met up with my ex and we ended up having mutual oral sex. When I was giving him oral I didnt have any cuts in my mouth, but now im concerned because I woas eating an orange in the acid from it made a little part of my gums burn. He didnt ejaculate in my mouth, but I believe a very small amount of precum came out and I swallowed it. He did not penetrate me or anything but I am just concerned with my sexual health because I am a paranoid health freak. Also another thing, I was rubbing his penis and his balls yesterday and this morning I awoke with some skin peeling of the hand. Could this be something I need to look into?? what is my risk??
