These are, literally, the 50 most popular songs about sex ever, as based on each song's performance on the Hot 100 chart.
"Slow Motion" - Juvenile feat. Soulja Slim
Hot 100 Peak: 1 for two wks (8/7/2004)
His moniker might be Juvenile, but there's nothing infantile about the way the New Orleans rapper raps his sex game. While Juvie may not exactly be whispering sweet nothings in his girl's ear, he sure knows how to get her attention.
Sexiest lyric: "If you loving my bark let me bury my bone/ I got 4 or 5 bad merry b****es at home"
"Feel Like Makin' Love" - Roberta Flack
Hot 100 Peak: 1 (8/10/1974)
The 1974 hit song for Roberta Flack garnered the singer and producer three Grammy nominations and sealed her place in baby-makin'-music history. Simple and to the point, this smooth groove was the gathering clouds for the future quiet storm revolution that would take over R&B a decade later.
Sexiest lyric: "When you talk to me, when you're moanin' sweet & low/ When you're touchin' me and my feelin's start to show"
"Pillow Talk" - Sylvia
Hot 100 Peak: 3 (6/9/1973)
You know you're on to something when your song is too sexy for Rev. Al Green. The soul legend reportedly turned down this steamy number before it was recorded by Sylvia in 1973, who was more than happy to spend a full two minutes panting, sighing and talking dirty in Spanish. ¡Caliente!
Sexiest lyric: "Ooh, I don't wanna see you be no fool/ What I'm teachin' you tonight, Boy, you'll never learn it in school"
"Pour Some Sugar on Me" - Def Leppard
Hot 100 Peak: 2 (7/23/1988)
Today's arena-sized rockers just don't do clever come-ons like they used to. Def Leppard's fist-pumping anthem celebrating sexual release still stands as one of the '80s all-time greatest, with a chorus even your grandma can hum along to.
Sexiest lyric: "You got the peaches I got the cream/ Sweet to taste saccharine"
"Bump N' Grind" - R. Kelly
Hot 100 Peak: 1 for four wks (4/9/1994)
There are two things R. Kelly doesn't see anything wrong with -- one of them is bumping and the other is grinding. The baddest boy of R&B puts his sexual desires on front street on this steamy track, as he let's the woman of his desire know that he can bust her pipes better -- and more often -- than her current man can.
Sexiest Lyric: "See I know just what you want and I know just what you need, girl/ So baby bring your body to me"
"Unskinny Bop" - Poison
Hot 100 Peak: 3 (9/1/1990)
Before Bret Michaels started looking for his "Rock of Love," the Poison frontman preferred his ladies with as few strings as possible. Guitarist C.C. DeVille has confessed that the phrase "unskinny bop" doesn't really mean anything, but that hasn't prevented listeners from using their imaginations.
Sexiest lyric: "You're sayin' my love won't do ya/ But that ain't love written on your face/ Well honey I can see right through ya/ We'll see whose ridin' who at the end of the race"
"Sexual Healing" - Marvin Gaye
Hot 100 Peak: 3 (1/29/1983)
Marvin Gaye entered the '80s with this "do me" classic -- making him one of a handful of artists who helped men seal the deal over different decades. With its gospel-style chant and 808 drumbeat, the song remains the template for contemporary R&B slow jams.
Sexiest lyric: "Baby I'm hot just like an oven/ I need some lovin'"
"Love To Love You Baby" - Donna Summer
Hot 100 Peak: 2 (2/7/1976)
Donna Summer's epic 16-minute orgasm, set to a thick, throbbing Georgio Morodor beat, helped usher in the 12-inch single and the extended remix -- not to mention many an extended bedroom sessions in the sexually-free '70s.
Sexiest lyric: "Do it to me again and again/ You put me in such an awful spin"
"Lady Marmalade" - Labelle
Hot 100 Peak: 1 (3/29/1975)
Christina Aguilera, Pink, Lil' Kim and Mya rode this classic to seductive success in 2001, but Patti Labelle and co.'s tale of a bi-lingual New Orleans call girl -- and her ability to leave men crying for more, more, more! -- really dropped jaws in the '70s. It's more than enough incentive to bring tourists back to the Big Easy.
Sexiest lyric: "Voulez-vouz coucher avec moi, ce soir?"
"Slegehammer" - Peter Gabriel
Hot 100 Peak: 1 (7/26/1986)
This '80s smash by Peter Gabriel doesn't sound particularly sexy, but a good read of the song's lyrics will leave you red-faced, as the British singer weaves a tapestry of sexual innuendos involving steam trains, honey bees and "big dippers." What, you thought it was about work tools?
Sexiest lyric: "Open up your fruitcage, where the fruit is as sweet as can be"
