That'd make a great concept for one of those relaxation CDs. I can just imagine the smooth, even tone of the voiceover guy on the TV ad: "Kick back, relax and unwind with... The sounds of f**king."I swear at one point a couple of weekends ago, there was even a song that I'm almost CERTAIN had sex noises in it...
It'd certainly be a change from whale noises or pan pipes.
