I had protected anal sex (GAY) 4 days ago, but unprotected oral sex, for around 10-15 second. I am really concerned because I have 2 small mouth ulcers on my upper and lower lips,they were not bleeding, and i heard HIV can be transmitted through them.
The guy i had sex with told me he got HIV test,negative, last week, but also had sex around 2 days before me.
So what is my chances of contracting HIV?? I am worrying sick please help!
