Honestly just the fact that you’re asking and are showing the self awareness is pretty great.
I haven’t been brave enough to actually seek therapy past a few very generic counselling sessions in university, but I think the most important thing to me would just be someone who doesn’t invalidate my existence. I identify as asexual and one of my biggest fears in going to therapy is for my sexual identity to be medicalized and dismissed, as I’ve heard many others like me have experienced.
