I've never had unprotected sex, orally I have but never otherwise. This past week I woke up with a big "spider bite" lookin sore on my right buttock along with another itchy "bite" on my back thigh as well as rectum itching. Now a week later they aren't as red and don't itch as much, I don't see and puss filled bumps or anything like that. Could it be herpes, I also play football which I red can cause a skin rash when sweating a lot. Any suggestions based on that?
