Pain during sex

Hey ladies, so I'm prone to UTIs and yeast infections and I'm 90% positive I don't have one at the moment. But during sex I'm in a lot of pain. Even when we'll lubricated. This is fairly common for me and I can usually work through it, but right now I'm still hurting. Vaginal burning is the only way to describe it. Can someone help me figure out what's going on??
