Hello! About a week ago i had male to male anal sex. i was the bottom in this situation. The partner was using protection however used his saliva as lubricant. a few days later my butt started itching and hurting. i looked at it and it was very red and irritated. i knew that i should get an STD screening right away. i went to my nearest clinic and got screened for clamydia, syphilis, gonorrhea, hiv, hep abc. They did not test for hpv or hsv. i looked at my butt again today and its gotten even more red with new bumps. could this possibly be herpes?
