Good question! Was wondering that myself lately. I suppose it’s difficult to find topics to post about that actually drive engagement without being overly horny or going into personal detail.
Edit: I remember drawing the map heart in HS. Never thought I’d find a community. It’s good to see it again.
In highschool, I used to doodle the girl love symbol on my notebooks and casually keep them open on front of people I was curious about. The symbols aren’t that wildly spread, so the knowledge of them required to recognize them on-sight generally is a good indicator. And if someone recognizes it in a bad way, it’s easy enough to deny as just a design you thought was cool
