Men vs. women streotypes

Well first let me say that men definitely stereotype women more than woman do . let me give you a example a guy is dating this girl but on the side he still talks to other girls . he tells his friends and his friends think its cool and its alright for him to do that . but if a girl is in a relationship with a guy and talks to other guys. its a problem and she called tramp or doing something she shouldn't . thats a stereotype . I feel if a guy can do it a girl can to plain and simple.
