Hah I feel that. For most of my comic's lifespan I haven't really advertised it as queer, maybe bringing up gender and sexuality when the topic arises, but it never felt like a real queer/LGBT+ comic. Calling it such felt especially weird since all the other slice-of-life and drama queer works tended to have more focus on romance or LGBT+ issues, while mine focuses more on mental health and trauma. There is small discussion on sexuality and gender, but not enough for it to be a major thing, and they're not talked about in the blunt way they're usually brought up in more queer focused works.
I've become more comfortable with labeling my comic as queer after thinking about how maybe having a comic like mine under the tag might give other people like me, who have no interest in romance or stories where being LGBT+ was the focus, something else to read. Also I was thinking that maybe it would encourage more hurt/comfort or dark queer content creators to be comfortable with sharing their work under the tag as well, since it tends to be saturated in fluff, melodrama and romance. (No offense to creators of these types of stories, or people who enjoy consuming them! These stories are totally fine, I just like my dark stuff.)
Anyways! I won't post my comic here since I've promoted it in the other queer stories thread (I think), just wanted to pop in to say that I can empathize with how you feel. Lol
