Something I mentioned on my demi tumblr a little while ago:
I was definitely demisexual in my teen years and didn't know it. I even came across a Timehop post I did two years ago trying to figure out why I did things so differently. I don't remember what it was about, but I'm sure my newfound identity might have played a part in that. Now that I've found AVEN and a whole community on tumblr, I feel better. It's a good feeling, and I hope others can feel that about their orientations.
Happy Pride Month!
