He has to catch me on my down-cycle. If I've just fallen asleep or am about half way into a deep sleep, he knows if he tries he's going to get his ass kicked. Literally. I will flail, remove his hands from body - dead serious. I have been told that I will grab his wrist as tightly as I possibly can, squeeze it for good measure then sharply drop it onto his chest in a very obvious "don't fucking touch me" tone.
Drives me insane because when I'm awake, I don't want him to stop touching me and I never mind being woken up for sex but at a certain point of my sleep cycle, I cannot be touched. He always jokes that a burglar/potential rapist would have nothing on me. (Which isn't true, I'm 5'1 and weigh 100 lbs soaking wet. This is why we have firearms.)
