Sexy dancing/lingerie/anniversary?

Ladies I need some advice big time. I've been with my bf for almost a year now, our anniversary is in August. We've been thru a lot and it's been a very interesting year. I have anniversary gifts for him, small things with a few that are sexy and few that are cute. I also have an outfit planned out somewhat to surprise him with. I want to make it special for him/us because I love him and I also like dressing up for him from time to time. I'm ok wearing the outfit but I would like to give him a little dance but I have no idea how too and if I'll be good at it. I'm also really self conscious and even though he says he loves the way I look idk if I'd be able to dance for him without laughing at my awkwardness. Any tips on how to become more comfortable dancing sexy or what music to play while I'm doing it? I really want to make it special. Thank you!!!
