Tertiary paraphilias are non-sexual and non-romantic paraphilias. I personally find it a very interesting topic.
Mine are blood, gore, extracted teeth, mold, bones, corpses, abandoned buildings, and probably some more that I’m forgetting. I can’t really explain why my attraction to those things feel paraphilic, but it does. It’s arousing, but not in a sexual way like my other paraphilias are. I do not posess romantic attraction towards anything.
ME!!! I physically can’t feel sexual arousal for some reason and when I do feel anything akin to it it always hurts or at least is very uncomfortable. SOMETIMES my autozoophilia makes me feel like that but whenever it does I stop whatever I’m doing because I’d rather not be in pain lol. But there’s plenty I can do and think about that falls under tertiary attraction.
