I switched from having my gender blank on facebook to setting it to male a few weeks ago, and my friend messaged me today with "why does it say that (female name) has written on his wall post?" I sent her a message saying that I see myself as male and am glad that the notices are going out this way, as I prefer male prounouns, and she responded "Ah cool, makes sense." Doesn't really count as completely coming out as trans, but I'm still happy about this, as this is the first time I've discussed anything with someone close to me.
