This is 100% true...I too knew a guy in high school who could say anything he wanted to girls or women, and they would still be all over him. He took down teachers, older guys girlfriends, married women, it was basically a game to him. It is a complete double standard but the women don't care. It is all about who is saying it, not what is being said. A woman knows within the first glance of a man whether or not she wants to have sex with him, before he even says a word. You only get that one first impression, and it is completely based on looks and confidence. You need both to succeed, but if you have both, success is easy.
