Umm. I am always down to have Fort Christmas or Jeremy Larson in the background of any activity, including sex.
During my first sexual relationship, my partner and I collaborated on making this goofy sex playlist that we’d always listen to, and it had some silly stuff like “Let’s Get It On” and burlesque music, but it also had some actually sexy music, like John Mayer circa Heavier Things and John Legend circa Once Again.
My friend Jamie introduced me to this band called the Gotan Project years and years ago, and they do wonderfully sexy instrumental music – tangos, jazz, etc.
8Tracks also has a lot of sexy playlists; you can do a search and find some great stuff.
