It made me feel uncomfortable for a couple of reasons some of which I left out from my post.
She has no boundaries, I wouldn’t put it past her to have came up to me and tried to look if I was using a urinal instead of a stall.
I have bad anxiety especially in situations involving conflict so I was pretty nervous that someone would start a fight
As a trans guy myself it’s a bit belittling to see my friend who I had opened up to before about the struggles using public restrooms opening using the mens restroom while she identifies as female and was dressed extremely feminine. It’s even more belittling when I mentioned this to her and it was just a joke to her.
