We had sex and he said he’s “used to different”

I’ve been talking to this guy for six months and we finally did it. I know he’s much more experienced than I am but since he said that I just feel so insecure. His exact words were “it wasn’t that bad, I’m just used to different”. I know obviously the first time won’t be amazing but I’m really overthinking it. I didn’t exactly love it either but I didn’t tell him that because I didn’t want to hurt his feelings. Just worried he’ll lose interest now. Do you see a problem with what he said?
