Gnat beat me to it. I am firmly against with holding sex (mostly because I would suffer more) but I have used that line when justifying a new saddle purchase or fit adjustment. And not because I'm being manipulative but because I simply could not tolerate sex because of chaffing and pain. One thing I can say for sure is that he stops bugging me about spending money on a saddle when I bring the topic up.
