Booty shaking

So my boyfriend loves my butt 😂 But he says that he wants me to like give him a lap dance or like shake my ass for him like in a sexy dance. I just don’t feel like I’m hot/confident enough to be sexy while doing it. Have any of you ever done it? Do have any booty shaking tips? Confidence boost? I really want to surprise him with a night of seduction but I feel like a fish on land when I try to dance sexy 😂 I want to turn him on like crazy, and would love any advice you have!!
