Immature men are the ones who keep chasing after ever woman who looks hot.
Immature men are never satisfied, their eyes linger around, any woman will pass them and they ogle, they are to be found on the Facebook photos of beautiful women commenting suggestively, they flood inboxes of women with "Can I have your number?", "My penis is nine inches long", "Are you a virgin?", "Can we meet, my wife won't know", "Can I can see you at your house"?
