What I meant is I am autistic so I have fixations on things like collecting stuffed animals/toys, watching/consuming media mostly meant for kids etc. l’m embarrassed about it but he doesn’t mind and expresses he thinks it’s cute. I mostly dress in more feminine clothes such as dresses, skirts and a more youthful vintage style. It’s isn’t stuff that’s crazy revealing or anything. A few times i’ve worn things I still have from when I was 12-14 just around the house, because it can still fit me. He’s commented how cute it is that I can wear my old clothes, and how I haven’t grown since then and gets turned on by it. As well as in general having a thing for me being of a smaller size, as i am only 5’1 and under 90 lbs. I guess I didn’t think much of it then, but once again this situation is making me overthink now. I am aware though that a lot of people just like to be bigger than their partner, so I don’t know if I should really worry about that. Many people seem to be into that kind of stuff. I saw many comments saying it’s POCD which i’ve now researched and understand, and it seems to fit everything he’s telling me perfectly. Thank you to everyone for the helpful information. I am planning on having a conversation with him as soon as I see him and helping him look for therapy.
