I think that feeling's not uncommon at all. I'm androgyne and pansexual, so personally I'm flexible all around. But I find that a lot of lesbians don't like to date bisexuals. Which I'm technically not, but I can see how some people might see me as one. I think some straight guys would have a problem with the fact that I half want to be a guy, and wear mostly guys' clothes too. That or they just don't see me as someone they would be interested in. A slight problem since most guys I like tend to be straight, but hey it's their loss. Most girls I like tend to be bi, so I guess it's ok there. In the end, as long as you find someone who can accept you for you, and love you for you, who cares what orientation they are?
