Doing it while sleeping

This actually is a real advice from a tea lady in my wife's office.

If you are too tired or too sleepy or whatever 'too much of', as a woman, you are capable of having sex while you take your rest. You just need to sleep or rest or whatever, while your partner or spouse or whoever on top, do all the work.

Easy right?

For women of course but just wondering whether men can do it like this too?

Or wants to?
