It's your wedding you can do what you want, but it is traditional for the couple to have the first dance of the evening, where they will then be joined by everyone else. If dancing is not your thing you don't have to. A lot of couples do not have a DJ or Wedding band and just enjoy the company of their guests over good food and wine! You could hire a Magician to entertain at this time and I have performed at a few weddings that did exactly this. They did not want loud music and just wanted to enjoy the company of their friends and family with some extra magical entertainment.
