What about asexuals?
What about men that have respect for their SO and don't see sex as the final goal? I mean, stay with the same person long enough and that part of the relationship will not be as important after a while, does it means the relationship is dead to the man? Because I can't explain why people stay together for decades then.
Don't most women have the same expectation that entering a love relationship with someone will lead to a physical relationship at some point?
You're talking as if women didn't have sexual desires and... Well... Maybe you don't, but your experience isn't the majority's.
