Age old question: Why is it when men and women are dating, in most cases, women are very liberal with the BJ's ?

Before we were married, my wifes face was buried between my legs, swallowing and all, never complained, never said a word, and 95% of the times she initiated the act.

Now...zero BJ's, and she makes no bones about her dislike for my cock in her mouth. And that is what is common place for couples who have been together numerous years.

Why...Tell me Why ????
