Around 7 weeks ago, I had gay experience. There was no penetration but there guy was rubbing his genitals on my anus without a condom. There might have been an attempted penetration but I didn't feel any pain so I don't think there was any successful penetration. It was my first time ever and it felt uncomfortable so I stopped immediately and there was no exchange of body fluids. Now after 7 weeks I have red circles on my upper inner thigh. They don't itch or burn. 3 or 4 circles, the size of a small finger tip. they look like burns but they don't burn. I used to have rashes in that area way before my one time sexual experience and I never panicked. Now I am seeing things differently cause I am constantly worried about STD's. Could They be an STD ? Or an allergy ? Or what ? Thanks
