Public Sex - AskMen

Public Sex - AskMen: "I moved to this country one year and two months ago. One of my big fantasies and turn-ons is having public sex. I just love the thought of others watching me and my fiancee having sex in front of them. We have done this before in South America before we moved, but we still feel unsafe and unsure to do it here in the United States. How accepted is this in America, and is it legal or allowed anywhere?"
