I'm only out on these forums. Don't feel the need for it IRL. My best friend also knows, but we don't really talk about it except for the off comment about butt-fuckin'.
I am very sexually ambiguous though, especially in my humor. So much so that I'm routinely asked if I'm gay lately (I started picking up the ante a bit in recent months, after watching a video about introversion that I really identified with.) and to that I always reply 'no'. Not because I'm super ashamed of anything, but I just don't identify as gay. I'm bi, and sure, you could argument that there isn't a huge difference between gay and bi, but at the end of the day I just feel like for most people it isn't any of their damn business what I am, and thus the answer is a resounding 'no'.
If I ever find myself in a long term dedicated relationship with a guy though, I would come out. Not worried about that either, my parents and sisters are awesome, acceptive people. And any friend that can't deal wouldn't be much of a friend anyway, so fuck them, right?
To the OP: You look very nice in that! Quick question though; is that your real hair, or a wig? (Not trying to be offensive or anything, just wonder because a lot of crossdressers go for a wig to get some extra oomph.)
