errrm, not too sure, I stopped playing (will continue later), but
Alone Amongst Demons may fit.

You are a male human, get your body stolen/ switched by some succubus, and then are a succubus/ girl in hell who must not be found out. And urges come up, and basically you WILL need sex to survive (that's what I got, as said, stopped for the moment)
main reason I will some day continue is this foreshadowing cg I saw (you're the one speaking to herself):
reason I stopped is poor gameplay design, and writing as if a 13yo on cocaine who sometimes actually throws fits.
