wow, so glad my current gf doesn't do any of that sh1t described in that article! I'd ditch a chick in a heartbeat if she was trying to play games with me like that...in fact I have ditched a chick like this before she could cheat on me (only got 2 weeks in) and then never looked back.
They nailed it right on the head when they spoke about women who see intimacy as an activity rather than something to be cherished. If your girl has a track record of choosing abstinence and loneliness over the spontaneous feeling of getting some, then you have a keeper. At that point its a matter of being ready to settle down with her for a while.
