Yawhi Or Cain With Reasoning

Basically, I’m fine with germs unless it comes to certain. For example someone touching me that isn’t really a problem for me. But when it comes to older things like a old book(books in a public library) or baby pictures meaning they’re old pictures. My brain automatically just goes germs or some shit like that. If I were to even try and touch those things I would start gagging. Another example is when I’m on mangago and I see a manga with a older cover I’ll just feel like I could smell and I’d try to avoid that manga as much as possible. Which is also the reason why I only read manga online. Does anyone also goes through anything similar to this?
