I am an 18 old male. I had unprotected oral sex with a sex worker (female)last night and I have a oral ulcer. Is there any risk for me to get inflected HIV or other venereal disease. And is it necessary for me to take a hiv test? I am worrying about zhis a lot. Someone please advise me! Thanks a lot
Oral sex, even with a mouth ulcer, is NOT a risk for HIV.
It IS a risk for other STD's and I recommend you have a complete STD panel done. (Your local health department does this free of charge as do most HIV clinics)
