Many of them do. My sis and dad read them and i show them all my art, since they're very artsy themselves. My mum doesn't get it too much but she's supportive nonetheless.
I kinda shove my art in the face of my friends from time to time like "LOOK AT MY CHILDREN" and some of them, who either are into comics or are super supportive, actually read the comic from time to time which is super sweet
And my gf is like my number 1 fan so she definitely reads it x'D I show them all the scripts and pages and she helps me with future plot decisions™. She knows all my stories, I know hers, we just help each other out a lot and gush about how we love our characters so much hahahaha
Hearing her scream at the panels like "ALPHONSE YOU LOOK SO HANDSOME AAAAA" brings me all the joy and motivation I could ever ask for
