Is it weird my boyfriend's mom gives him massages?

I've been dating my boyfriend for 6 months, and if I've learned one thing in those 6 months it's that he's a mama's boy. In theory, in fine with that, but he gives her more time and attention than me especially since I'm away at college. His mother gives him massages which I think is weird even though he has been having some pain lately. For example, I was home Sunday night and gave him a massage, and then today I didn't hear from him for like an hour (despite trying to contact him) which I later found out was because he was getting a massage from his mother. I think this is so weird, especially since he does it with usually his shirt off and will pull down his pants a bit when on his stomach so she can massage his lower back. I've voice i think it's weird and he seems to not care, saying his parents have seen all of him naked before so it's okay. Am I crazy? Or is this weird?
