I don't know that there is any music that on its own actually turns me on.
But there is music that goes well with sex (not too distracting, good rhythms etc.) - and if I have had some particularly amazing sex to a certain song etc - I am likely to recall those memories when hearing the music.
Right now for "sexy" music I would have to say Glass Animals. I have had some WONDERFUL experiences while their Zaba album was playing.
Hum - reminds maybe I will set the mood tonight by putting some on.
