Sort of, but I'm not wholly sure I agree with it.

They are basically saying "when you have multiple Parts, you literally cannot control what another Part does with the body." Versus someone without DID who may struggle with self control, but they are only trying to control themselves, not a Part that can physically hijack the body.

I'm not sure what the full story is with your sexual part or why it's considered a danger, but I do agree that working on communication with ALL Parts is essential to being functional.
