I mean, I’m a kinda ABDL. Although I’m trying to quit because it grosses me out now. My one therapist I told was super accepting. But I’m not sure about your case because my therapist said my coping skills were ok since they weren’t a danger to myself or others.
But yeah our brains are mysterious. Everyone has their thing though. I wouldn’t be too hard on yourself unless it became out of control. But please seek out a therapist to talk to about this.
