Shy around my husband

We are together 9 years and there’s a part of me he hasn’t really seen. I used to study dance until my teens and we’ve gone to clubs but it’s not the same, so he hasn’t really seen me dance and I’m just overly shy, I think I’m just afraid of his reaction. For the longest time I’ve been thinking of doing burlesque dance for him and the only way I might pull through is by drinking a few shots to give me some courage. Our anniversary is coming up and trying to chill TF out!! Is this even normal for a wife?
