In 1992, she moved to Los Angeles, where she lived with her grandmother, and started to work as an exotic dancer. Her first on-camera work was for a Penthouse video, while her first porn role was in the VCA movie The DJ.

In 1995,  After her second son's birth she got a breast enlargement and signed a contract with Elegant Angel. Patrick Collins, Elegant Angel's founder, dubbed her Buttwoman in 1997. The movie of this title, which she starred in, was her breakthrough, although she was a popular performer prior to this release. It was the start of a torrid career that featured her in numerous videos, many featuring blowjobs and extreme anal sex with well-endowed men, and often these scenes were interracial. In addition to her anal scenes, her seeming eagerness to receive a facial cum shot has also earned her fame. She also starred repeatedly in foot fetish scenes, and was often in lesbian themed films.

In 1998, she wrote, produced, directed, starred in, and even did some costume design in Asswoman in Wonderland.

As of recently, Tiffany has starred in more than 350 porn movies and has directed The Toe Story. She owns two production companies, Pagan Pictures and Tiffany Mynx Productions. In 2001, she was inducted into the AVN Hall of Fame.

Some of her more recent work has been for the Evil Angel production company. Recent titles include work with director Jules Jordan, including Once You Go Black, You Never Go Back 2. She also appears opposite Jules in Ass Worship 5 where she uses the soles of her feet to bring him to climax.
