I know it's a meme (kinda), but it makes sense for Succubi to find hand holding lewd. Succubi are sexual demons. They're all about lust not love, so of course something as intimate as hand holding would be like asking for fisting or some other shit.

Holding hands restricts what you're able to do and puts you in a vulnerable position should your other decide to turn against you. Holding hands means being able to be dragged to places you don't want to go. Hand holding takes very genuine trust.
