Attraction works very differently for men and women. Obviously we are attracted to the opposite and our brains operate quite differently, so you can't justify how MM doesn't work based on how a man's mind works.
Psychologicaly speaking, our brains work very differently, and that includes attraction. What a man wants is different that what a woman wants. That being said, the way attraction builds in a man is different than the way it builds in a woman.
Actually this can be proven in terms of evolution. Without boring everyone to death, I'll make it simple. Our main purpose in life is to reproduce and survive so our species can continue to thrive. As a male, we are designed to reproduce with as many females as we can so we can increase the percentage of survival in our offspring. If we didn't, we risk the possiblity of extinction by not producing enough offspring that can survive. If every male did this (not reproducing to the max) during the dawn of our species, we would be extinct.
For women, however, they have to be more careful with whom they reproduce with because it is a much bigger decision for them. Unlike men, they cannot "spread their seed". They have to spend the next 9 months giving birth to one child that can hopefully survive. That being said, they must be very picky with whom they decide to sleep with. If they don't they'll end up sleeping with a loser and now they have to spend the next 9 months giving birth to a weak offspring that will surely die. If every girl did this, then our species would be extinct. A guy doesn't have to be picky because if a certain offspring dies, he must not worry because he has also slept with countless other women hoping that their offspring would be much stronger and fit for survival.
This explanation pretty much sums up everything about humans; attraction, survival, and our actions. Clearly, attraction is very different for men and women for the obvious reasons said above. Men shoud have sex with a lot women, while women need to be picky and "test" men to see if they have any value for the sake of their offsprings survival and the species as a whole.
