Hiya Troy.
I like your additions. Best, I liked the change to your final paragraph (that was the one line that made me respond to the original as I did.)
I've heard of "bisexual guilt," that is, where the bi person feels like, hey it's so unfair to my gay/lesbian friends that I get heterosexual privilege! so they throw themselves deeply into activism projects. I guess one can go either way about going either way, huh?
