There’s no need to upset someone with pronoun use, when you are in the same room with them. ‘You’ works fine.
And while some TiFs may pass, when they’ve chosen to out themselves to access support and are suffering from historical abuse, I can’t imagine any sense of them being male remains. No one can read that description of sex based abuse and maintain anxiety over the sex of the sufferer.
The TiF I know and love is very tall, and has had a full mastectomy. There’s still no way they pass, once you know. Maybe, if you didn’t know.
