qiute honestly,what you're doing is being a jurk!sorry, but you dont take a girl out for lunch and then expect her to pay for her own meal...its your treat, your money that should go into it..
besides that, women are not whores...you cant buy sex from us...
if thats what you want then find a real hooker!!
you've got to treat a girl with respect and make her feel special before you get ANYTHING ;let alone sex; from her.
i hope you learn something from this,
plz change your ways for the better and
good luck
