Pulse rate increase could add to sexual excitement.  Just like the beat of a drum, the beating of your heart is the best recipe of an enjoyable lovemaking.  It would increase your adrinaline and could add your fire… 
Other couple enjoyed loud metalic rock when making love,  wild movement which go with the rythm of the music played.  Other uses slow instrumental music.  All the same, the best is to use your pulse beating.  Try to listen to your partner’s heartbeat and yours.  Notice that you both have the same tempo?  Try to make it faster, surely  it would make your blood flow faster and  and  increase the heat that both of your body release. 
Music really is a good medicine and the best recipe to a promising lovemaking.
Now, dance with the music…
