At 20 she first ventured into the adult industry, appearing in establishments for adults and moving on to her first amateur hardcore video "Orgia di compleanno" directed by Cesare Geromini. Her decision to pursue a career in porn was driven by exhibitionism and, in her words, her passion for sex and the need to rebel against society. Her parents disapproved of her career, which was out of embarrassment at their daughter's career choice. Her breakthrough came in 1993 at the age of 27 when the director Alex Perry offered her a role in the film Signore scandalose di provincia, a film with a high budget and international cast. From that moment her popularity grew rapidly and she adopted the stage name Selen. She has been called Italy's favourite porn-star. She made appearances at the Hot D'Or pornographic festival in Cannes and Erotica in Turin and won 17 prizes during her career as a famous pornographic actress from 1993–99. Her last hardcore scenes were released in 2000 with the film Millennium. Although her last sex scene was filmed in 1999, she continued to appear afterwards in films as clips were used in later hardcore films. She has stated that she would not return to porn in the future – in her words, she was not enjoying the profession enough to continue.
