I would have to say for me it's my relationship with my boyfriend. When we met, he was very homophobic, and I don't think he would've even given me a chance as a friend had I not been born biologically female. By the time I had come to terms with this whole mess and came out to him, we were already very much in love and had a strong bond, so it made it easier for him to continue our relationship. Soon after, he came to terms with being bisexual and that there was nothing wrong with it. He says he doesn't know if he would've come to terms with it if it weren't for me.
Another awesome thing is that my feet are small enough for light-up shoes @_@!
