Hello, I am 25, and I have a burning sensation when I pee, and also discomfort in that area. I feel like it cld be a UTI since I recently had sex while using KY his and hers. No real other symptoms, except besides the discomfort, I also feel like I need to pee all the time, but I don't have to. Does this truly sound like a UTI, or could it be something else?
