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.
