My wife does not like for me to give her oral sex/pleasure. I have never been with any girls in the past that are opposed to receiving oral from me. I thoroughly enjoy it and feel, based on past experiences that I am good at it in terms of pleasing women and bringing then to orgasm.My wife’s response has always been that it’s dirty. I have tried and tried to convince her that it is not dirty and I really enjoy and want to give her oral. Any advice?
