Sexsomnia: Not as funny as it sounds Sexsomnia is one of those words that's both titillating and disarming to hear. It's the name for a condition in which someone has a sexual experience while asleep, sort of like how people walk or talk in their sleep. It spawns jokes from the people it affects and from the people who are lucky enough not to have to deal with this sleep disorder. I have never heard of such a thing in my life. Now, I talk in my sleep, and I've been known to sleep walk- but never this. If I hadn't come across this on my little cutie, Anderson Cooper's blog- I'd dimiss it as internet rubbish... I need to go to sleep now- no sexsomnia for me tonight, thanks!
