This is a great article, Victor. I have only heard the term “sapio-sexual” recently. It has probably always been around but just didn’t have a name.
What you say is very correct concerning most writers many famous writers were reclusive and didn’t like being in public. I am like that to a certain extent…I like to plan my words and am much more comfortable communicating with the written word than in person.
I can see how it is easy to fall for another writer, through their words, and common interests/intellect. After all the fact two people have writing in common is a big factor just to start with … then if you actually like what each other writes, well … the sky’s the limit.
