That is interesting, yes!
And it sucks - and kind of shows how books become boring when these things that give the author pleasure (and thus are probably written about more passionately) are self/edited out.

Me, I like....
Found family
Long hair on men
Friends who are physical (but not sexually intimate, particularly same sex friends)
Horses
Competence in a job, particularly if the person seems like they wouldn't be (like, for instance, a pre-serum Steve Rogers being really good at self defense, or woodworking or something)
Characters that cuss like breathing
Completely consensual but not exhaustively discussed rough sex
Artists (particularly artists who do art that involves a physical aspect, like how some abstract expressionists would climb ladders, fling paint, smash things, etc....)
A bit of PTSD or some sort of trauma in general that makes a character prickly and untrusting, but not completely cut off from life in general

I have, in fact, written probably close to a million words of my favorite thing in an original character/shared universe with my bff. It is awesome to do so. :D
