This may sound incredibly cynical and negative and I am very, very sorry if it does:
People, nearly as a whole, cannot reason. If someone has an issue with you, it's likely a symptom of the greater struggle that humanity simply cannot be logical about most things. People tend to act on what information they're given and cannot comprehend where it comes from. In other words, until society learns to accept us, people will more or less blindly reject us.
All that is important to a lot of people is to follow what trends make them the most acceptable, because acceptance is naturally associated with success. Transgender prejudice is really just an instrument of the times -- it will go away. I know that may not be a comfort, since it is still a problem now, but I do hope that you can find some peace in knowing that many people are sort of trained to be terrible to us. They don't really come to the conclusion that we're fake, all on their own, as some sort of deep, meaningful reflection. It's just knee-jerk stuff.
As for the boyfriend and boy-on-boy thing:
I won't lie. I some times fantasize about being flat-chested and having a penis (I don't think about the gender identity of it all, but I guess I picture myself as a typical "femboy") with my boyfriend. He would never go for that, and I honestly don't care for having a penis and am quite fond of my boobs, but what can I say? I think it's hot, and sexy-time brain is going to sexy-time brain. I blame all of those years of yaoi.
