The people who are questioning why you'd be with a man when you were supposedly a lesbian before are obviously not familiar with bisexuality/pansexuality. Unfortunately, the narrow-minded people of the world will always give those whose minds are open a hard time. Good on you for standing up for love regardless of genitalia; perhaps if the world weren't so binary-minded, transfolk would have a better time of things. I had a good friend in college, ten years ago, who was a staunch lesbian. Now, 10 years later, she's been with a genetic male for the past 4 years. Crazier things have happened. And how about all the "straight" men and women who end up in same-sex relationships? People decide that straight is the norm, and assume that if you're not straight, you must be gay. If only folks could get their heads out of their asses.
I'm ftm, and am with a cisgendered girl. The few friends of hers who know I'm trans have wondered why we're together, considering she had only ever been with bio-men before, but I just figure they're closed-minded and unfortunate for it. I could try to help you with some resources, but I'd need to know in which area you live. In the meantime, I'm happy to give any advice necessary--- you can contact me via personal message here on susan's, or add me on facebook:
