I’d be fine with consensual non-consent roleplay in real life, but I don’t want to actually get assaulted. Voluntary submission isn’t the same as being forced against my will. The taboo nature of the fantasy helps me confront my real fear and discomfort in a safe way.

It’s the same thing with more open relationships. I’d be willing to have me or a partner get dominated in front of the other, but I hate the idea of actually cheating or being cheated on. I wouldn’t want to violate my partner’s trust or have mine be violated, even if I never get to explore that kink because a partner isn’t into it.
