Since men are not monogamous, why don't they seek a partner who is also into non-monogamy?

Make this question one-sided because all the women cheat as well there are statistics that proves that men cheat far more often than women. And we all know that the fact that men are not naturally monogamous by Nature so I think that it is foolish for women to continue to get into monogamous relationships based on Fidelity thinking that the man is going to be faithful to them when it is mostly never the case.

I keep hearing men say things like we want some new v**ina every once in awhile and that we should just accept it because they just want a variety. Then why is it wrong when a woman wants a variety of men as well. When it comes to men cheating and being unfaithful then it's because "monogamy isn't natural" but when a woman cheats then she is called a "304" and is told that she is for the "streets".

My issue was that men are always calling themselves leaders but never want to lead by example when being honest and transparent about their true intentions when getting into a relationship with a woman they would much rather lie about wanting monogamy then being honest about wanting to be polyamorous and rather seeking a woman that shares the same relationship interest. Basically we live in a world where men want to have their cake and eat it too where they secretly desire one-sided open relationships where only they are allowed to have multiple partners while their woman remains monogamous and unfortunately that is not how life works. Women are always taught to normalize what hurts and bothers them and yet men are never held to high standards and it's only up to the woman to uphold morality and honesty while men are allowed to do whatever they want without any consequences. I am just so tired of the double standards here.
