I begin with a shower. Then I shave. Interestingly even these are crucial rituals to the transition from one gender to the other and I notice distinct changes in persona, mannerisms, emotions and self-image.
I think basically we often design our own rituals to be the stimulus and guide to that transformation.
Eventually that transformation seems not only to require less impetus and to occur with greater facility but that characteristics, traits and other behaviourial patterns tend to adapt to either gender.
