Does liking shemales make you gay?

[muverick]

Hey everyone, I was about to ask the question of if it's gay or not to be aroused by ts girls.
Not for the sake of putting myself in a category, just for curiosity, to see what the general opinion is.

I've got a girlfriend (who sometimes puts on a strap-on during sex ), I am not attracted to men in anyway
I just normally assumed I'd be kind of "bi" due to the whole cock attraction of ts girls? Maybe semi-bi-sexual?
