My daughter snapped a photo of me while I was out on the front veranda this afternoon. This is very much non-binary me as this is what I wear (or similar) most of the time.
Contrast this photo with the 10 year old photo of biker girl me posted above.
The way I see it is that I don't have facial hair, I've got boobies and I've got about as much T in my system percentage wise as there is water in the Sahara Desert so I don't have to prove anything.
