There's also the expression to "follow me/you down", as in the song "Baby, Let Me Follow You Down". In that case it means to have sex with someone (in the general sense, not specifically in the oral sense). Buffy Saint-Marie once did a delightfully sassy song with the chorus:

"Ninety-seven men in this here town would give a half a grand in silver just to follow me down, so appreciate a dedicated baby, cos boy, you are a lucky ma-a-an!"
