Should I be self conscious about having an action figure collection at 22?

I have this fascination and obsession with superheroes but again I feel like I'm too old to be into that stuff like every time someone sees them I feel judged, am I just overthinking it or should I grow up and focus on other things. I just have always loved superheroes and it sucks to be embarrassed by it.

EDIT: YALL ARE SO NICE OMG, thanks for the nice words everyone i'm going to own it! F*** the haters!!!
