I have found music and sex an extremely awkward combination in this relationship. I feel like I'm dancing and it makes me feel silly--and I can't dance in front of my partner unless I've had a lot to drink (I do like to dance, though!). Our primary way of playing music is through media players on our computers and we don't usually make lists, so there are some weird things that could come on. 1970s anime music, for example?! I have tried Futurepop (a branch of electronic music), and I recall a time when Loreena McKennitt was playing.
I seriously think death metal sex could be hot.
