I'm the opposite of you, in this area.
Until you've been with a selfish partner, one cannot appreciate an unselfish partner.

At the same time, there's men who find it an ego boost, and if your partner is laying out a guilt trip, by taking it personal, seems selfish in motive perhaps, perhaps not??

Depends on the scenario, and if it's just the act, and then feeling slighted that you didn't merely have an orgasm from it, that could be why.

Not sure...
