I'm pretty sure I'm straight, so I'm attracted to men. Half seriously tried to start liking girls a couple of times but I could only get as far as platonic friend love even if I managed to make out with them tbh; I'm apparently really not sexually attracted to girls. I don't mind though, I'm perfectly happy with a man c:
I guess my orientation defines me a bit, and I think it does for others too. It determines where we look in life, what we strive for, and where and with whom we want to be. In no way do I think that's a negative thing, rather it's just a neutral observation about human behavior. Even if we're asexual, that affects and determines those things as well.
