Why is she withholding sex?
Did you do something bad to her? In the west, men are so puzz whipped that women can control men sexually. men dont want to jeopardize their chances of getting it. Either she doesnt want to talk to you anymore, or she wants to try to control you. To control you she needs you to think that her vagina has priceless value. You should confront her with the problem, find out why, then threaten that, if theres no sex in the house, ill just get a take out order.
That myth about women wanting sex as much as we do, needs to be cleared up. When a women is pleasured right, she loves and enjoys the sex, probably more than men. But men's hormones want the sex more. For men, the orgasm is just relieving some testoserone. I know for a fact, if a guy comes out of a relationship and doesnt get it for 2 weeks, hell be feeling like he wants to nutt on something. After two weeks for a girl, shes good. Attention is what women want. its the equivalent of an orgasm for us. If shes cut off from attention, she will go crazy.
