1) Men: "I have to want her to want to have sex with me"

2) Women: "I have to want to have sex with him"

Most Women know most Men probably want to have sex with her. However, just because he does, doesn't mean she will enjoy it. She won't receive validation for unenjoyable sex with a Man she doesn't like. Dick is free, commitment from a Man you truly want is not. Better to stay alone and hit the vibrator.

Most Men know most Women probably don't want to have sex with him. If she wants to have sex with him too that's a real anomaly. He won't receive validation if he has to pay her, because she still doesn't actually want to have sex with Him. That's why although prostitution is more popular among Men, overall most Men don't feel validated by prostitutes and don't utilize them. It's just not the same.

This is what you will see Women/Men complain about respectively. Women not getting validation from adequate suitors to fill her non sexual wants. Men not getting validation from Women (most of whom are already adequate to have sex with) to satiate his wants.

No one wins. Men/Women complaining are due to not getting what they really want. No need to demonize either side or hate the other. Life isn't fair and nature/universe doesn't care. We are just built this way and it is what it is.
