I can't believe I'm actually making a thread about this...

I would have titled it "Sexsomnia", apparently the proper name for sex-related stuff during sleep, but all I've ever done is the title.

I did some research, it certainly happens and is a bit more common with women than men, but all I wonder is...why? The only reason I'm aware of this in myself is because every once in a while I'll wake up with my legs splayed and one hand in just the right place (especially odd as I never masturbate like that while awake). I never thought much of it until it popped into my head again today and I went to see if it's a thing.

I had an thread here a while back wondering if my combination of low sex drive and outright anxiety/fear about sex constituted some kind of disorder. I read a bit of speculation that sexsomnia might be caused by a lack of satisfaction in waking life, or a result of repression. I...really hope neither of those are the case.

So, anyone know about this? It's not a problem, just something I'm a bit weirded out by and wondered about.
