he'll never be refused???

One of the many ways in which I'm a fortunate man, is that my wife is a willing and avid lover. But in 26 years of marriage, there have been at least three times, maybe even four or more, when I have started to initiate something and she has mentioned that, for one reason or another, she just didn't feel like it. But she really loves me, so ultimately she just went along with it after all.
          Yeah,...right...
