That's silly. There is a difference in risk between sleeping with every crackwhore to come down the pyke, and sleeping with a steady girlfriend who you know well.
If you say you never really know them well enough, well that's true even if you marry them -- he could still get AIDS or STD's from his first sex after marriage.
There is no "risk free" option. There are only matters of degree. He's chosen a silly level.
Not to mention that most girls I have met are nut jobs and/or gold diggers regardless of how big their boobs are, or how good they look in a bikini. Bikini girls grow in trees.
Whats the point of thinking inside of your pants and ending up in lifelong misery? Its extremely stupid.
If the girl even implies that she either a) likes, admires, enjoys, or has ever at any point in history dated a "bad boy" she can go to hell. I will never be friends or respect or even talk to her. If we are on a date or even 6 months in, she's gone. Or, b) if she says that 'guys have to treat me like a queen'... forget it. She has the wrong attitude.
Its not that I am going to be mean to her, but she has to realize that if she is going to date me its going to require her own work and effort and a selfless attitude of doing something for someone else.
Then again I am not yet 33 or close to it...hopefully they grow out of it.
