You don't think that might backfire and put him in that frame of mind that he should always go after the loose girls, and not bother with those with morals and a good outlook on life? I mean, once you start a pattern like that, it's difficult to break...and that's why a lot of the guys I grew up with have date rape on their records, because they were always expecting it and even when the girl finally agreed, the next day she regretted it and totally fucked their lives up...
Just a thought.
