All About Intimacy:
Not In the Mood:
Arousal and Anger

At times, a man or woman who does not get aroused is angry with their partner for some reason. They do not wish to show their anger for some reason, but instead they withhold sex (perhaps subconsciously) as a ´punishment´. If this seems to be a problem in your relationship, try talking about it at a neutral time, when you can explore it openly and honestly.
