Rub it out and then let her know you can take care of business without her. Otherwise she thinks she has you in the vagina ViseGrips and bargains from a position of strength. There has to be more equality. Withholding sex is not how it should work. One or both of you should start communicating effectively instead of being assholes. Suggest indulging in grudge or hate sex for a while with lots of name calling and swearing, but talk afterwards don't sleep. It's like fighting with pillows or assault with a friendly weapon. What do women want? fucked if I know but if they think they are holding all the cards (sitting on them actually) it's way more difficult to find common ground.
That'll be $0.05
.....wait....name calling and swearing isn't part of the routine ?
