Actually it does. A succubus by definition is a submissive sex demon and an incubus is a dom sex demon. yes, succubi are generally seen as female and incubi are male, but its purely based on them being generally dom or sub in the sexual sense. If you're generally dommy, you're an Incubus

however if you're generally submissive, you're a succubus. They aren't gendered terms just like how witch, wizard, warlock aren't gendered terms either
