I began to notice this burning sensation followed by a stinging pain when my boyfriends penis is first inserted . I had also noticed that when I would pee it would burn and went to the doctors and was positive for a UTI . I got an antibiotic for it and took it for 8 days . I thought when we would have sex it would burn because I had the UTI . We haven't had sex at all until after the medicine was done and my doctor said that it's surely gone . It's been about 2 weeks since we've had sex . Just yesterday we tried and I felt that same pain , the burning feeling . It just hurts right when the tip is in around the wall but not deep down and then the pain goes away once in for awhile . Just the initial insertion stings and burns . I'm not sure the reasoning . It makes me not want to have sex because of afraid of the pain .
