My wife and i often share Tina time, but it is always AFTER the transformation. I, for one, don't particularly feel comfortable "in between" genders and don't particularly like that transformation ritual interrupted. Once transformed, Tina is very happy to share ideas with her girlfriend ("his" wife) and we have a really terrific time, and that can include changing outfits, makeup, etc.
I'm sure we all have a spectrum of feelings about the transformation process, and for those who are less binary about their gender presentations, I can see where one could have fun sharing in that transformation process.
