Was this a bad thing that my friend said? Or am I overthinking?

So my friends and I were watching “Mike and Dave need Wedding dates” and there is this scene where there is an inappropriate massage scene. I’ll link it:
doesn’t show the whole thing bc again its rated R very inappropriate scene. The movie takes place in Hawaii (US) and when something inappropriate was happening my friend asked “what country is this in?” Kinda laughing. I said united states. And he said in a chuckle “I’m having a hard time believing that xD” and I don't know why I thought it was an off comment my mind immediately went to “are u saying that can’t happen in the us or something?” I might be taking it too seriously. Am I? Was is a rude comment of him? Again the movie is pure comedy so he could’ve been joking or whatever. It was the “I’m having a hard time believing this is us” part that got me. He himself is NOT from the US just a disclaimer. Am I overthinking?
