Ok, so this is intended for serious responses only: in today's world, when do men know that they are "men"?
Interesting responses....I figured that a few "penis size" answers would come in, but I don't think that the size of a man's genitalia, or how often he has "indulged" it in play, determines if he is a man or not....J. if you want to ask this question about women, please feel free to do so, but this question is about how men define that they are "men".
