Just a thought.
What if he gave the girls $100 each, to just have a "sexy" evening, that was limited to just watching the "show"? How exciting to be there, but not enough to get some "wood". They may have said that the rule was, "no touching", unless invited. Why not? I would go to a party like that. I can tell you that I would be dueling with the one eyed dragon a bit later.
