Do you urinate after sex? That helps prevent UTI's!
possible but it may just be your vaginal tract is just not lubricated enough. try unscented lube. hope this helps
Is it always an UTI? Could you be allergic to condoms? If this is in fact an infection it could be a number of things. Like laundry soap/body wash or some lubricants. He could be using lubricants by himself and not realizing they affect you. I couldn't rule out cheating but it can't be ruled in either. Good luck I really hope it's an easy quick solution:)
