Favorite music to F### to. :) ;)
Barry White, Johnny Mathis, and that genre have presided over billions of fun and frolic sessions, and may have presided during more conceptions that any other entertainers I can think of. In my situation, since most times there is a hotel involved, I simply tune the clock radio for whatever sounds nice at a medium volume without sounding too much like elevator music. Although I've done lots of up and down rides (of the biblical kind) to good elevator music.
I like the hard stuff -- Alice in Chains, Soundgarden, Shinedown, Halestorm -- but I have a real soft spot for Ted Nugent's Stranglehold. When I was a young man, I had my first really intense lap dance to that song. It was at a club where they let the entire song play and it's a long one! The song has a great "in and out" rhythm for two bodies intertwined! Thanks, Marsha, wherever you are ...
