Yep. It's a tiny little nubbin until they're mating. Then it's gross and alien-like as most penises are.
Maybe you should feel thankful that you don't turn them on.
I see one every night, no lie. I have a male neutered cat and he LOVES my stuffed animal on my bed. He romances it multiple times an evening.
I read online that even if a cat is neutered, he can still get aroused and enjoy participating in sexual activities. I just let the h0rny little fella enjoy his friend as he isn't hurting anyone by it LOL
My sweet baby Wonton did this too with his stuffed froggie. He loved that toy.
