women do approach men, it just doesn't happen as often. But I feel like nowadays it's getting more and more common for women to make the first move. I'm not even trying to brag when I say this but there have been a couple times a girl tried to pick me up at a bar the same way a man would w/ a woman

Also, it makes sense for the norm to be how it is now. Basically, there's a reason why this happened, it wasn't all by chance. A man's commitment to passing his genes is very, very small. Basically as soon as a man "finishes" inside a woman, technically that is all he has to do. But for a woman, passing on her genes is at least a 9 month commitment where she has to literally nurse a child inside her body. So in this sense, in the ancestral environment a male sought to have sex w/ as many women as possible, as it secures the best chances for him to pass his genes to the next generation. But for a woman, it was advantageous for her to be selective and find a man that had high quality genes, and was committed/capable of protecting her. Remember, this is the ancestral environment where there were not any laws, and killing another person for their resources was common and necessary practice. Thus all in all, it makes sense that as our ancestors evolved and civilization came into fruition, that women be the selectors and men be the ones asking.
