She was attending her first quantum physics expo with her roommate when she realized.... She was sapiosexual.
Here's a word to have fun with. Sapiosexual is your word of the day which is in dire need of a sentence. (?)
Background---I once worked with a gay man for about 10 years. He was HIV positive, but a long term survivor at the time. We kidded around a lot, but he never made a pass at me.
Sentence as requested---In retrospect, his restraint with regards to me was admirable since he was sapiosexual; and he finally eventually admitted that he loved me for my mind.
