the last thing i/we listened to during the sexing was black sabbath. i think any variety of stoner metal would probably be good. (am listening to graves at sea right now apropos of a comment on p.1)
i would probably also want to listen to various top 40 hip hop type stuff, but she hates it.
i usually listen to screamo when i watch porn... i don't know why. i don't think she likes screamo either.
