I don't see foids fantasize about being succubi in their erotic novels. Even though they act a lot like them. Maybe they don't want to acknowledge the fact they themselves are literal semen demons within their souls.
Succubus are also perhaps a very male oriented fantasy, having females that desire strongly to have sex with you, but you have to resist it and so you get to fight and kill too.But I think a lot of women would want to be demons who suck men's souls out through their dicks and burn their souls up in their personal belly of hellfire. Seems very foid-coded.
