Popular music has always been horny as hell, but used to have more lyrical fig leafs. When Elvis sings about parking where it's nice and dark, it's not to play connect 4 (especially given it didn't exist yet).
- “Hot for Teacher” Van Halen, 1983
- “Love in an Elevator” Aerosmith, 1989
- “Cherry Pie” Warrant, 1990
- “Shook Me All Night Long” AC/DC, 1980
- “Paradise by the Dashboard Lights” Meatloaf, 1978
- “I’ll Make Love to You” Boys II Men, 1994
- “Baby Got Back” Sir Mix-A-Lot, 1992
- “Black Dog” Led Zeppelin 1971
- “Brown Sugar”, The Rolling Stones, 1971. Off the album “Sticky Fingers” no less
Those are just the ones off the top of my head. But yeah IMO music hasn’t really changed much. People have and continue to love singing and listening to songs about bonin’.
"I Didn't Like It the First Time", Ida Lee, 1947 (aka the Spinach Song ;) )
"One Hour Mama", Ida Cox, 1939
"It's Tight Like That", Clara Smith, 1929
And the most explicit of all these, "Shave 'Em Dry", Lucille Bogan, 1935, which makes some modern music look prude in comparison. (originally Ma Rainey in 1924)
