We use to have music on during our lovemaking before kids. Then we played the quiet game where the music was very soft. Then as the kids were out of the house at friends and relatives, we got into soft jazz, most had no vocals . It had some good stroking sounds.
We have a play list 'sex music'. Started out as a joke, but it's a regular thing now. Since it's getting to be that time of year, the fireplace videos add a nice ambience to the bedroom and has just the right light, too...with many choices of background music.. However, I do not get points for subtlety when she come upstairs and finds the fireplace on the TV.....
