Femininity is a greater evil, poorly understood, which is capable of inviting men to perform all kinds of vile acts.
It makes sense.

You can still masturbate toward succubus if you have strong visuals. It can help to find images online, especially if very unknown characters or peoples' OCs. Basically just don't know who they are in any source material (a name is fine). Because, your succ is different but they can "be represented" by them since it's just a spirit. Granted this is really just training wheels for better visualization.
Since humanity began talking to spirits we've used various real world media to depict them, it's really quite natural and jacking off to a statue of a goddess was par for the course
