Absolutely spot on. Jodi would have used her sexuality to manipulate men from a relatively young age (I'd guess early to mid teens) but other girls and women would have been nothing but competition. I also believe she thought she was pushing boundaries sexually - especially perhaps to a Mormon man relatively inexperienced in relationships - deliberately to make herself seem superior to 'normal' girls. She would have let Travis do anything he expressed having fantasized about - not because she was humiliated and subjugated but because that was her hook all along. She used sex and every emotion it drew forth as a means of control, manipulation, coercion, etc. To make him feel ashamed; threaten to 'out' him; to increase her importance.
However, though Jodi views women as competition I feel she'll use absolutely anyone to her gain and that has me concerned. If she's ever allowed in gen pop, my heart truly goes out to the women she's allowed access to. Female institutions are full of very vulnerable people that can be easily victimized and ill-equipped to deal with the likes of Jodi.
If permitted, I don't for a second believe she'll ever be done hurting and using others just to get what she wants. Ever.
