Re: you did it for other men, but not me?
Put aside the anal, BDSM and threesomes.
Let's say they talked before marriage and she told him that she either didn't do oral sex or hated it. He decides OK there's enough other good stuff here, let's get married anyway.
10 years later they have drinks with this girlfriend, and it comes out that his wife not only did oral sex but loved it, told her girlfriend and everybody else how great it was to take her sex partners to the stars with BJs. She loved the taste and the whole experience.
I'd say there would be plenty of reason for him to say, well, now that I know you like it, how about a little sumpin', and that's one of my fondest fantasies.
If the answer is simply "no," without any reason, I think he'd be well within the zone of reasonableness to say, "WTF?"
