I used to shag around. Now I don't. What happened? I'm not sure. I think it's because I fell in love with someone who was extremely horrible to me and now I see sex as being that thing rather than the fun it used to be.
If she steals people's boyfriends and sleeps with a whole rugby team that seems a bit far, even by my standards, and shows a complete lack of caring for the publics opinion. Have you asked her why she does what she does? Does she think her behaviour is acceptable? Or is it more she can't see an alternative? Is she just having fun and not realising it looks bad or trying to prove something?
Psych help is prolly good anyway.
