There's something to be said about setting the mood when you're about to get busy with your boyfriend. Some people like candles, others like bubble baths, and a lot of people like setting the scene with music in the background.
I actually prefer no music whatsoever, but if it's quiet enough and has no words, then I'm cool with it. What about you? Do you like music playing while you're getting it on? If so, what kind? Sweet, gentle background melodies? Loud rock n' roll? Erotic, sexual music? Or do you not really care?
