I've long held that my personal sexuality is irrelevant because I'm married. I'm married-sexual, as it were. But that ignores the help it can do to share publicly with others who may struggle with the fear of being different.
I have considered myself bisexual since high school, have had relationships with men and women and married a woman. I guess these days I'd have to amend that to being pan since trans people are sexy as hell too. Never dated one though.
