I have had unprotected sex with a new partner for the past couple months. Oral,Vaginal and Anal. 3 weeks ago I developed a red spot (not sure if it's a sore, it is not wet and does not seem to be open) on my penis head. It's about half the sizeof a dime and has not changed in appearance at all over the past 3 weeks, once it seemed to be a little rough almost like it was going to scab, but after a shower it was smooth again. It's not painful or itchy unless I'm having rough sex or rub it hard. At first I thought it might be just a mark from rough sex, but again no change in appearance or feeling in 3 weeks. I'm thinking maybe herpes type 1?
I should mention that my new partner did have an STD test and came back clean. She does have cold sores and I believe she had an outbreak once during oral, but I'm 90% sure I had cold sores as a child but never had outbreaks since a teenager and I'm 33 now.
