I agree with DP, alot of chillout/ambient is good for sex. 
You should all try Are You Shpongled?. It was wicked but gooood  
  
Any track that arouse those feelings I can't really think of at the moment. It's more like when I hear tracks that was on during sex, when I hear them again I think of sex  
  
Vibrasphere - San Pedro (Low Sky Rmx) 
Abakus - California Sunshine 
I could picture good love making to those songs
