I'm in favor of the genetics arguments myself considering it does makeup the base value of someone's personality. Though sociological and psychological factors must always be considered since sexual orientation begins to form during puberty. Now I admit I have found some transgender females physically attractive, but have never had the urge to sleep with them, no. Now to answer to your question, Ryuki, I don't think that makes me gay. For those who are sexually attracted to transgenders whose have the same genitalia, I honestly think there needs to be a new word cause it's not man/woman with man/woman, but man/woman with man into woman/woman into man. My problem is most people confuse the LGBT community with their personal orientation with morality. That's a problem! They always religion as a excuse that is a tired and bullshit idea to explain their fear of their lack of understanding. I have heard the procreation arguments with usually stating the extreme of what if everyone became gay, and no baby were made. Well I say there are too many different personality types to let that happen, and cloning is now possible.
Of course, those same people also think Transvestites and being gay is the same thing. Look at Eddie Izzard, he only likes women but still likes their clothes. Or how he explains it:
