Why worry about how the Church defines anything?  Simply call yourself Catholic and life as you wish to.

The two biggest "alt" Catholics right now are probably Andrew Sullivan and Milo Y.  Both are gay, but both have partners and reject the Church's  unreasonable live-as-a-celibate rule.

People with gender-whatever, be Catholics if you wish to.   We are all equally unwelcome here,  equally unable to achieve holiness as the Church defines it in its 10,000 rules.
