He doesn't want to see you naked he just wants to see a woman naked, he is just curious. He heard this interesting story so he wants to see it acted out.
What you need to do is explain that is not an actual courtship ritual and it is inappropriate for him to ask to have it acted out. If you don't sit down with him next will be his babysitter, aunts, nice lady next door and you will be known as the woman with the six year old pervert!
After reading Suz's response, yes, do not make him feel bad or make it personal. Just focus on explaining the inaccuracy of the story while including that women will not just dance naked for men, they just don't, whoever told him the story was embellishing.
What do you mean by early awareness? He heard a story and is discussing it. If he hadn't heard the story he wouldn't be aware. If I am told about a great product that my neighbor hasn't that doesn't make me early aware, it means I was told it first.
With this post and your one before you need to pull yourself away from some of this. You are not reacting well. Any parent who just heard this story would not have immediately jumped to Oedipus complex! You do get that was a seriously irrational leap? You think your coworker is in love with you even though you have never lived as a couple, I doubt you have even farted in front of each other. That isn't love, that is infatuation! Now you think your son is in love with you sexually. Perhaps you need to discuss with your therapist why you feel you need to be sexually loved, what is missing that you need to feel. Do this before whatever is going on messes up your kids as well.
