Sex in public has a dangerously appealing ring to it. Unfortunately, when it's called lewd and lascivious exhibition, not so much. You may have heard recently about the Florida couple arrested for having sex on the beach. They were found guilty of lewd and lascivious exhibition, when a young child caught them in the act. This is a crime, if it's believed that you engage in an intentional sexual performance in the presence of a child younger than 16, that can lead to serious penalties.
