Why don't you already have a transsexual girlfriend?

I myself live in London and have made friends with quite a few tgirls. Sadly getting to the relationship stage has been very difficult. I almost lead 2 lives which I'm getting sick of. It's only a matter of time before i confess all to friends and family. They know of my foot fetish but saying i like tgirls maybe a bit much, but then in order for me to be truly happy i must tell everyone so i can move into this area which I love so much.
