Swollen male genitalia.

I hope someone can give me an answer if this looks normal or not. We just got our male Chinchilla - his old owner had him in a starter Chinchilla cage and on wood chips. We recently upgraded him to a Ferret Nation 182 and on fleece. Just last night my daughter held him and I noticed how red and swollen his male bits were. I'm wondering if this calls for a vet visit.. Any help is appreciated.
