How can a person enjoy performing oral sex for 4 years, and then all the sudden just decide they no longer like it. My wife knows I like it, and thus she should WANT to do this for me, just like I enjoy pleasing my wife with oral sex. I have performed oral sex on her HUNDREDS of times, and there are just as many bodily fluids exchanged when A man does a women as when a women does a man, so this "Gross" thing is for the birds.
