When do you "meet the parents"?

My guy and i have been together a few months, and I’ve already met his parents…which to me seemed crazy, but he said it isn’t a big deal to him. For me, I think that meeting the parents is a big deal…it shows that person is extremely significant. My family is important, therefore incorporating that person in that is a big deal, and I have held off because of that. However, this is more general…do guys feel differentely about “meeting the parents”? What are your experiences?
