Sexsomnia
From Wikipedia: Sleep sex or sexsomnia is a form of REM behavioural disorder (a parasomnia) that causes people to commit sexual acts while they are asleep.
Yup. I have an ex who did this ALL the time. It wasn’t like goodatpoetry2 describes. It would totally be like he was awake. Much more like you, kittenkisses24, describe. He’d be totally asleep, though, and unaware of what he was doing unless I woke him up — lots of shaking him and repeating his name. He’d kind of “come out of it.” And be surprised.
It’s kind of sad… I actually preferred his, uhm, style when he was asleep over when he was awake. He was a lot more enthusiastic. Like he just couldn’t help himself. Which, come to think of it, he couldn’t, I guess!
