I think most of you must know what I mean by sleepy sex. I think it tends to happen more often in long term relationships. And I for one advocate it and love it. When it comes to my husband and I, it starts out sleepy and ends up kinky.
It usually happens when we've been flirting with one another all day and one of us goes to sleep before the other. Then he or I will get into bed and start fondling and playing. Usually I resist for a while because I like my sleep and as a full time mother I am truly knackered at the end of the day, but it doesn't take long for him to do something to make me feel horny. While he usually doesn't resist much at all, even if I wake him up in the early hours of the night. He doesn't even care if I've come up to bed horny because I've been watching sexcetera 
He doesn't mind being used as a piece of meat when it comes to sleepy sex...lol
For some reason though, we never seem to go from sleepy sex to slow love making. It always gets a bit wild and we end up waking one of the kids or feeling sleep deprived for a few days. But I wouldn't change it for the world.
