None of those apply to what makes a man "sexy" though. There are other things that men do to make themselves look sexy though. (Think sleeveless shirts, tank tops, button up flannel shirts rolled up to their elbow, a suit, v-neck shirts, a well-fitting pair of blue jeans... etc.)
Sometimes I like to wear a tight-ish t-shirt that makes my arms and chest look bigger than they actually are.
Rationally speaking women make more efforts to attract men,they try to change what their actual look are,such as i said changing the color of their eyes,hair...etc.
What is the purpose ? i don't think just to get married because even married women are doing the same stuff.
