I recently had an encounter with another male where our penises rubbed together (one week ago). He told me he was completely std free and gets tested regularly, but one can never be sure. The next day, I went for a long bike ride without my body being conditioned for the rubbing, etc. The following day or two later, I developed a rash a lot like jock itch between the scrotum and thigh, but it has seemed to go away. However, I used some creams and powders (one with tolnaftate, one with clotrimazole) and that helped the rash, but there is still minor itching, and now the tip of my penis is somewhat numb and there is a slight burning sensation at times. There is slight discoloration in the head, with a slight roundish blot that is a bit lighter. I have no lesions or blisters, no other physical symptoms of herpes.
I was previously std free, but have a paranoia and have become very anxious and stressed, which I know can cause certain things. But I'm very worried about this. What do you advise, or what might you diagnose this as?
Thanks!
