Strippers who uncover the genital areas along with other clothing during a performance are said to be dancing fully nude. The fully nude practice is banned in many jurisdictions, but many dancers work around these constraints by selective uncovering of the vulva, anus, or both, for short periods of time, followed by immediate replacement of the clothing. Not all strippers are comfortable dancing topless or fully nude. Strippers can sometimes be contracted for performances outside the strip club environment.

Inside the club, personal boundaries are frequently crossed between strippers, customers, and other club staff. Research indicates that at some point every dancer has felt exploited by customers, management, or other dancers. The most common complaint from dancers
