Teachers are normal crushes. We spend a lot of time around them in our young, impressionable years. So yeah. haha. My first actual crush crush was on my grade 6 home room. I thought she was sooooo hot. Lol.
The worst crushes to have, in my opinion, are ones on friends. Especially if your crush is not interested in your "bio-sex", and can't get past it.
One of my best friends and I flirt all the time. She treats me primarily male, but she told me I was her "butchy-chook" when I discussed transition with her for the first time over 2 years ago.
On the plus, I spose, she seemed excited when we talked about testosterone a few months ago, and asked if I'd grow a dick

As much as I like her, she prob wouldn't be with me anyway
