Allow me to explain my strange sex education:
a) 11 years old, mom throws me a set of four books about sex for
kids. This is back in 1983. Some version of a "what's happening
to my body?" book.
b) 14 years old, I'm in the public library. I find an ancient
book:

which I read with fascination. Charts, statistics, things about
spectrums of attraction and such.
Never read the one on female though. Really I should get around
to it.
So, I've always had spectrum view of sexual attraction.
