Jane - I also love striptease and nude in public videos. You should go to a nude resort for a weekend. will cure whatever it is that is holding you back. My wife was really against going to a nude beach but after 5 seconds she loved it!! as did I.
Be brave. Life is too short to waste in delay. Just start your phone video in private, show your body, dance, pose edit and upload to xhamster and await the plaudits. That may give you courage to perform live before an audience. Great memories for your future...
