A sex show is a form of pornographic performance in which customers pay to see live persons appearing performing some type of sexual activity. The sexual performance may be autoerotic or with another performer an may be actual or simulated. Sex shows are distinguished from striptease in that sex show performers engage in sexual activity rather than simply undressing and dancing nude. Sex shows are distinguished from prostitution in that the performer engages in sexual activity with another performer or masturbates themselves for the entertainment of a customer rather than engaging in sex with the customer directly. Sex shows, however, do overlap with other forms of sex work; some strip clubs and peep shows offer live sex performances, and some prostitutes offer sexual performances with other prostitutes among their services.
