I'm actually a bit worried about coming out to my family about this. I already came out to my dad about my liking men, he didn't take kindly to it. I mean, it could have been much much worse, sure, but my dad, who is usually super cool, told me outright that I'm not to let anyone know that I like guys as long as I'm living with him. I'm pretty sure if I told him that I don't always feel so much like a guy, he wouldn't take it well. My step mom, I'm not sure how she'd take it. But my sister, I have no idea why but she's pretty outspoken about her beliefs on ->-bleeped-<-, and they're none too pleasant.
I dunno. I'm not full on MtF; if I were I know I'd need to come out eventually. For now, at least, I'm fine with forcing out my male self while around family. Maybe the day will come when I feel otherwise. Maybe when I'm finally independent enough to move out I'll tell him. But for now, when he's my only reliable source of food and shelter, I would rather not risk disappointing him so much that I get kicked out or anything.
