Fuck: Nine Inch Nails - Closer
Love: the sound of our own love making
Sookie Sookie Steppenwolf
Fuck: Led Zeppelin's 'Whole Lotta' Love", of course
Bridge (somewhere between just a fuck and making love): Led Zeppelin's "Kashmir", or something from Pink Floyd's "Dark Side Of The Moon".
Actual Making Love: Maybe some light background classical (Mozart or Haydn), but nothing that'd drown out our own sounds.
