Anus collision morphs.

[BeefyJackal]

Is there any type of UNP based body (or any other kind) that uses anus morphs in animations? I know that  BHUNP has vagina morphs in animations, but for the anus to work, an animator has to add a keyword to their animations for it to work. Are there any animations that do so?

Sorry if this is the wrong place to ask this kind of question.
