Not even in your dreams

This is one of the most hilarious stories I heard recently: a single guy who recently turned religious and stopped having sex told that his biggest frustration now is that in his dreams a sexy woman would appear and ask him for sex and he would say: sorry ma'am but I can't do that anymore! then he wakes up and starts banging his head against the pillow shouting at himself: it is okay in the dream! it is okay in the dream!
