The incredible success of Marvin Gaye's politically-charged 1971 LP, What's Going On, proved to the world that he had more to offer than his love songs of the 1960s – but when it came time to craft a follow-up, he had little desire to repeat the formula. Instead, he opted to record an album of funk songs that were extremely sexually charged.
The title track was the most successful single of Gaye's career, sitting on top of the Billboard Hot 100 for two weeks. The opening wah-wah guitar notes (played by Don Peake) ooze sex, and the song never lets up from there. "I can't see anything wrong with sex between consenting anybodies," Gaye wrote in the album's liner notes. "I think we make far too much of it. After all, one's genitals are just one important part of the magnificent human body."
