That sort of makes me wonder about FTMs who enjoy crossdressing as women, and might wish do so for their RLE (but might do something like wearing forms on top of a binder, tucking a packer, etc). Although I suppose that's neither here nor there. Doesn't really apply to me very much, although I'm somewhat effeminate. That's one thing that makes me worry; I'm a little effeminate, gay ("I like men, but in a gay way"), a drag-queen-in-training, and genderqueer, and I don't think I could really hide that from my therapist, not that I'd feel the need.
I'm simply not close to any of my teachers. My art and soon-to-be Spanish teachers are really the only ones I'd think would need to know, since I'll have them for my entire high school "life", whereas my core class teachers like history, science, etc. would only have me for one semester, and after that we'll ignore each other, so I wouldn't build any meaningful relationship with them. Other than asking to be called Christopher, which I don't think they'd question, I wouldn't see why they'd need to know. But, thinking about it, it may aid the confusion of, "Wait, I thought that was a girl student... why does she have a crappy little 'teenage-boy' beard? o.O;"
Peers, though, I'll be with those morons for a REEEEALLY long time. XD They were pretty much all told last year.
If my therapist turns out to be knowledgeable on trans* issues (won't know 'til the coming Friday) and wants me to come out to all my teachers as part of RLE, I can do that, no real problem. It might actually be a good thing -- they might call me "he". XD
I'd always seen a pattern here of MTFs starting RLE and HRT more or less at the same time, or HRT beforehand, depending on the situation. Although I've also seen the same for FTMs, just less.
