A lot of "sexy" music is just whatever beats and stuff. I'm looking for music with sounds of people fucking, especially women, or with explicit lyrics about having sex. Stuff that will really get me turned on while listening to it.
Hard mode: I'm a lesbian, so if it's a guy singing or talks about men too much that's a turn off for me ☹️
There's a great Spotify Playlist called "Bobby Hill's Sex Positive Boiler Room Set" that I subscribe to. It has all the things you mention. Women artist dominated, sex positive and horny.
"Sadeness" by Enigma comes to mind. There's a lady whispering and sighing over some cloudy blurry flute and percussion that puts you in a certain mindset. There's some Latin chanting (Gregorian chants?) that lends the song a sense of sanctity and also secrecy at the same time. I sound crazy but I think it fits the bill.
Sidenote: I also love "Full Bodied" by Ghost Data.
Stoker Ace by Lovage. It's much different vibe - jazzy and down tempo. I could see it as a break between more intense sets. It's got a sexy female singer talking as though she's a cat with a french accent.
