Lynn was a bikini and figure model in Los Angeles in the early 1980s; following this she was featured in magazine photo spreads for Penthouse, Hustler, Chic, High Society and Club magazines. Lynn's first adult film was Bobby Hollander's Personal Touch. In 1983, shortly after her photo spread appeared in Penthouse magazine, she went to an audition for a movie where the Director was a well-known porn veteran. There, in an effort to calm her nervousness, the Director offered Lynn a pipe with some freebase cocaine. It was her first encounter with the drug; she later described the feeling of being as, "It's as if the birds are singing. The light is brighter. All of a sudden I'm no longer this gangly nervous teenager. I'm sitting there going 'Oh wow!'".

Lynn has had roles in non-adult films such as Evils of the Night (1985) and 52 Pick-Up (1986), and in the television program The Man Show.

Lynn has opposed the Los Angeles "Safer Sex in the Adult-Film Industry" initiative, which mandates that actors in adult films shot in Los Angeles County use condoms. She has been involved in the first charity to accept contributions from the adult film industry, Youth AIDS Foundation of Los Angeles, since 1992. She also helps other charities such as Childhood Cancer Awareness, The Southern California Toy Run and Janie’s Fund, Steven Tyler's new organization.

Lynn's drug addiction ran for nearly two decades. She once said, "I started out drinking Ketel One and slicing off crystals of Peruvian rock. I wound up broken down, drinking Kamchatka Vodka out of a half-pint stashed in the bottom of my purse, with my crack pipe stuffed in the Li Ning of my jacket". She has been clean and sober since 2000, and occasionally works as a personal recovery assistant, helping addicts to detox. She also works in mainstream acting roles, as a webcam model on one of the largest cam sites online, and as a real estate agent specializing in luxury homes.

She is the sister of the late porn actor Buck Adams, who died from heart failure in 2008. On Lynn's second porn film she met Jamie Gillis, who became her long-time partner.

Lynn hosts a weekly talk show called Rock’N'SeXXXy UnCensored on LATalkRadio.com and Stitcher.com. She is a member of the Adult Video News (AVN) Hall of Fame and was awarded a Lifetime Achievement Award from the Free Speech Coalition. She continues to perform as an adult Actress, most recently shooting for Naughty America in April 2016
