No, we’re not talking about broadcasting the dying-cow sound of your orgasm for all your neighbors to hear. We’re talking about getting some decent speakers to put in your bedroom when you’re doing it to music. Tunes can really help set a mood. (There’s a good reason why movies always set the sex scene to surround-sound music.) But having those tunes come out of a tinny little alarm-clock radio on your night-stand can work against that mood when you’re acting out your own sex scene. You don’t have to go big or pricey. Get something like Cyber Acoustics Subwoofer/Satellite System: put a speaker on either side of the bed (for balanced sound) and — now this is essential — put the subwoofer under the middle of your bed by the headboard. Then just plug your mp3 player into the system and you’re good to go. If you don’t have a gift for making cool or appropriate playlists, try Pandora.com, one of the greatest inventions of the 21st century: you create your own “station” by plugging in a song or artist you like into their database, and they automatically and immediately create an endless playlist of similar stuff — all for freakin’ free! For perennially good dramatic sex music, try entering “Massive Attack” (but only if it’s dark out and you’ve lit some candles).
