Just ask him why! Be upfront about it, but not in an accusing manor. We could speculate all day about this, but at the end of the day, nobody really knows except him. Good luck!
I have a false teeth. My BF has a perfect beautiful teeth. At first when we are dating he would kiss me during sex, but recently I notice he won't kiss me on the lips while having sex with him. . Please answer this question. I need help?
The only thing I can think of is maybe your breath. False teeth need to be cleaned a lot and brush your tongue. Otherwise, I can't think of any other reason. Maybe you need a better cleaner and mouthwash?
