Bisexual, slightly leaning straight. Only ever had an intimate relationship with a guy, though, due to how much easier it is emotionally and socially (we're just friends with benefits now). Only discovered that when I was 19 or so; during my teenage years I never felt even a twinge of attraction to a male. I suspect that I could've gone from 1 to 2 on the Kinsey scale around that time after exposure to Japanese pop culture on the Internet or literature featuring LGBT relationships, which both happened around that age.
When _ozymandias posted zir introduction post a few days ago, I went off and binged on blogs from the trans/men's rights/feminist spectrum. I found them absolutely fascinating. I've always had lots of sympathy for transgendered people in particular, and care a lot about all those issues. I don't know what I think of making up new pronouns, and I get a bit offput by trying to remember the non-offensive terms for everything. For example, I'm sure that LGBT as a term offends people, and I agree that lumping the T with the LGB is a bit dubious, but I don't know any other equivalent term that everyone will understand. I'm going to keep using it.
However, I don't currently know any LGBT people who I can talk to about these things. In particular, the whole LGBT and feminist and so on community seems to be prone to taking unnecessary offense, and believing in subjectivism and silly things like that.
So I'd really like to talk with some LWers who have experience with these things. I've got questions that I think would be better answered by an IM conversation than by just reading blogs.
If anyone wants to have an IM conversation about this, please message me. I'd be very grateful.
EDIT: Wow, that's an amazing response. Thank you all for your kind offers. I'll talk to as many of you as I can get around to.
