|Can she face herself?|
But you still feel tense about the whole thing, as if one wrong word and the Femdom will go away.
If only she'd admit to enjoying Femdom! Or better yet ask for it! Then you could relax.
There's a good chance she won't anytime soon.
The position of a Vanilla Dominatrix is far more complicated than that of a subbish partner.
Morally, domming feels wrong. Nice people don't exploit, tease, humiliate or hurt their lovers, or anybody else. It takes a while to come to terms with being a little bit evil, and then to feel safe in admitting that to a partner. Perhaps she feels guilty because your kink doesn't turn her on, but all the things it provides does.
She may also want to control the descent into kink. Becoming openly enthusiastic might trigger more demands from you that she'll enjoy less. What else do you have lurking in the toy box?
Finally... well... there's the possibility that she enjoys you in a chastity belt more than without, and doesn't want to tell you this in case it hurts your feelings.
I know that BDSM culture has a strong emphasis on communication. However, that's between players who are already comfortable with their roles. In this case, wait and see.
If it ain't broke, don't fix it!
