Hey guys, I have a prob to deal with lol...

I currently have a gf been a week. Really pretty, hot, nice and bla bla, in one word, a good girl ! The problem is, my ex that ive been with for a year, and been 2 years I'm not with her anymore, sexually attracts me really BADLY. Everytime I date a girl or have a girlfriend, ****, theres not a single girl that matches my ex, sexually spoken. If you guys tell me to go back with her, **** no lol... Its only the sex that is good cause we always get into fight.. How can I deal with this loll.. Shes my fantasy... I want to get into a stable relationship but I always want to bang my ex..
There is NO girls that equals her.. None lol.. Passed enough of girls to judge this. .. Of course there is one on the earth but haven't found her lol...

**** testosterone ! =)
