Men's and women's mating strategies are adversarial.
Is the only (or best) way for a man to maintain power in a relationship/interaction with a woman is to fully engage in his optimal mating strategy (being honest about your polygamous nature).
I noticed it yields more returns and although chicks hate it (because they can't have the upper hand on you) they still fall and comply. Whereas if you're being "nice" and careful not to hurt her feelings and not hitting on or seeing other girls she begins to take you for granted and starts cautiously exerting her hypergamy.
it seems there is no win-win situation with them. it's either you win all across the board or she does.
