Like unprotected vaginal sex, unprotected anal sex is high risk for many sexually transmitted infections, such as chlamydia, gonorrhea, herpes, hepatitis, HIV, and syphilis. What are the chances of having HIV? I’m still getting tested but, this happened just a week ago. He precummed and cummed outside of my body well after anal sex but, still precum may have gotten inside of me at some point, I’m not sure. I asked him about his HIV status and he said he was negative but, I’m still not sure. We were versatile and used a lot of lube. I had unprotected anal sex with another man for the first time in over a year.
