While I can understand, and even appreciate, your feelings of frustration and desire to punish your wife by having her bludgeoned by the very thing she withholds, I have to say that the fun of fantasy violence and violation stops where the real blood begins spilling. If your wife won't put out, if the word "bitch" is what comes to mind when you think of her, divorce is a much better solution. When weighed against each other, alimony kicks ass over 5-15 years in prison for conspiracy to commit aggravated rape.
