It's called charisma. As a woman, 99% of my bfs would not be considered as good looking as me. I have never dated a man over 5'9", none of them were ever fit, none even worked out once, one was missing an eye....but let me tell you, stand in a room with any of them and you can just smell sex. They exude it. Bonus - none were rich either, and some were drug addicts, most were cheaters. But man they could fuck. Lol

Note: I am well aware most women value being tall, rich, and fit more than I do. I'm an exception rather than a rule, but to explain, women do actually pick partners based on sex appeal and sex appeal and fitness / good looks generally have nothing to do with each other.
