My boyfriend watches iCarly and Sam & Cat?

So I saw my boyfriend watching iCarly and Sam & Cat on a few occasions now. He didn't try to hide it from me or anything but there is something very offputting to me that my 31 year old boyfriend is watching a show for preteens with preteen girls in it. That being said, he also watches a bunch of cartoons like SpongeBob and other stuff on CartoonNetwork, but that stuff just seems silly and harmless to me. This seems... weird. And kind of paedophilic. Am I overreacting? I told him how I felt about it as gently as I could but he still got upset.
