I'm certainly for trying not to give oneself a label but I also understand trying to come to a better understanding of yourself.

I'm in a somewhat similar boat. It's awkward for me to write, but over the last few years I've found myself looking at more and more gay oriented material when I do look at pornography. This is strange for me because I have never found myself emotionally or romantically attracted to any men at any point in my life.
Also, I snap out of it the moment I see a guy's face. As soon as I see a face, I'm just like "Ew, gross: You're a person.... you're a guy!"

So, yeah, I don't think people should be in a huge rush to designate themselves as this or that. Just be you.
