"Sex (I'm A...)" is a song by the American band Berlin from their second album Pleasure Victim. The song was co-written by group members John Crawford, Terri Nunn and David Diamond and sung as a duet by Crawford and Nunn.
Released as the album's second single in February 1983,[1] the single, influenced by Donna Summer's seminal "I Feel Love", became a cult hit on American radio and brought the group into the mainstream. Despite the significant attention, the song's racy lyrics resulted in its being banned from several radio stations.[2] The single peaked at No. 62 on the Billboard Hot 100 for two weeks in late March and early April 1983.[3][4] The song was also the first single release from the band's new label, Geffen Records.
According to disc jockey Richard Blade, the song's lyrics referenced his relationship with Nunn.[5]
