I always thought the “different expectations” prejudice about relationships was more about average men wanting a “body to fuck” that’s also a pleasant person and average women wanting a pleasant person that’s also a “body to fuck” (you know, the old adage about push-up bras and lies).
I don’t know if it’s also about how much is your body attractive to your partner, to me it seems like an unnecessary requirement and kind of “objectifying yourself”. Like, if a person is in love with your personality and finds your body simply “attractive”, is that not good enough for a relationship to you? That situation is like hitting a jackpot for most men I know.
