So a week ago, I started feeling very itchy when wearing light wash jeans, and I was with my significant other. Yesterday, we had sex (keep in mind i’ve only had vaginal sex with him). He stated his penis was “burning,” and thinks I have an STD. I have been with nobody else but him, but he had a previously been with a girl. I had my blood drawn a few months ago, and they didn’t tell me I had anything wrong besides a UTI. My vagina hasn’t been burning but it has been very itchy, I’ve debated that I have a yeast infection but I am unsure why his penis is now burning?
