Instead, it's Olivia Newton-John who is tops - her hit "Physical" is No. 1, followed by Rod Stewart's "Tonight's the Night (Gonna Be Alright)."
Rounding out the top five: Boyz II Men's ballad "I'll Make Love to You," Next's "Too Close" and Marvin Gaye's "Let's Get it On." (Gaye's "Sexual Healing" is No. 35)
It's not until No. 10 - Stewart's "Da Ya Think I'm Sexy?" - that sex is mentioned in any song title.
Billboard's list, released Thursday, is based on the popularity of songs from 1958 until early January of this year.
