yea, sexuality as a binary is pushed on people so much, but when it comes down to it, it doesn't work like that. Honestly, how many things in life are black and white? I think a lot of people like simplifying sexuality down t 2 or 3 categories because thinking about it in real terms is too scary. The subject fascinates me really. I'm trying to read every good book I can find about it.
My advice? Stop thinking about definitions and labels. Those things are so other people know how to judge and interact with you. They don't need to know those thigns to get to know and like/dislike you, or whatever, it's not important. Focus more on what you enjoy and what you don't. If you like it, go with the flow, explore it. That's what the early years are for. Don't live with regrets. If you want to try it, try it. Just make sure you can trust whoever you might want to try something with.
I can relate, really. When I was in high school, I let other people define me, and turned into the "gay guy". Truth be told I don't fit the mold. I don't find women disgusting (

), and could very much enjoy bedding with one (if you could handle all this--sizzle

) The world wants you to be something specific, so it can discard you and move on, or "embrace the mold", and keep you wedged in there. Forget about the world. It's okay to build your own mold, the world will still be there when you get back...
p.s. if anything sounds drastically wrong or like a terrible insult, just let me know--I didn't mean it like that.
