Trust me when I was your age I had the biggest crush on my female teachers, I still do and I graduated coming three years ago.
Some girls form crushes purely based on how beautiful other women are, 你 are definitely not a freak. I am 110% sure of that. Trust me. Both sexes no matter how old 或者 how straight will always say "now that is a hot/gorgeous man/woman" trust me even men admire other men.
