I use both . . . mostly M because that's what is on ID.
LAWFUL in this state to use either, but I present border male most days. On days when I present "more female" I look 67 and matronly -- male hormones in geriatric decline. Older people look "less sexy" & thus less gendered.
Presenting "F" entails using cultural gender signifiers -- hair, jewelry, clothing, handbag (laptop bag), accessories like scarves, hats, shades. Choose settings where strict standards are off, people diverse, anonymous, like race tracks, casinos.
Objections are met w/ "transitional" sorry that I made you uncomfortable. And then leave.
BUT -- cis-F remind me that they use restrooms for menses mgmt. Males in that space are cause for alarm about sexual assault and related.
Tough issue because it's crucial to ID how one "presents" in social contexts.
When presenting "F" -- I use handicapped, "family" w/ lock on door.
