Funny how, when the roles are reversed, the media and society treat it far more severely. Equality much? There will always be people who are attracted to younger mates, which is not wrong unless the mate is under age. A gap of four or five years is drastic when in your teens, but ignored entirely in your late 20s. It's not the age difference that's the problem, it's the age of the youngster, who hasn't even really had time to figure themselves out yet.
Anyone in a position of power over another should not have any sexual contact with those they are in charge of. This is not rocket science here people. This is also why I think that teachers will be soon obsolete so that this can not happen.
