Does it help to keep in mind a distinction between gender identity and gender expression? Dressing for me isn't simply a preference for an activity. It's an expression of a feeling, a need to express a feminine aspect of my being. That does not alter my gender identity. I like lots of things. Expressing all of me, including my soft side, is who I am. It's not just another thing I like, like a book or TV show.
That this is who I am doesn't impinge on my gender identity. It does change, from time to time, my gender expression. It is more than what I like because it's an inextricable part of my personality.
