Now there is an interesting thing here... ever seen or heard of a AFAB cross-dresser?!
In the terms used for MtF, >90% of AFAB would be cross-dressing, yes?
Though it might bring about an issue with FtMs, as most every one and there uncle's first guess would be --- you being lesbian, butch, not lipstick though, obviously.
Now how do YOU deal with that, being FtM? Ignore it, correct them?
In fact dressing 'down' (jeans, tackies, t-shirt, pony tail, no makeup) may just make me be considered just that... butch-lesbian. I wouldn't give two straws as I'm BI, so long no one calls me a guy or dude, eh! More complications?
Best be, I guess, to have an introduction, even by oneself, stating your name.
It should side step the issue, won't it?
