In no particular order (basically whatever pops in my head):
The texture of the seeds in a fig on my teeth (especially in a Fig Newton)
Chewing on a straw (my major stim)
The sound of trip hop/electronic/experimental music
The sounds/smells/sights of the seashore (I grew up on the beach)
The taste/smell of curry (especially mixed with coconut milk)
The feel of my cat's fur on my hands/feet
The sound of Alison Krauss, Beth Gibbons (Portishead) or Skye Edwards (Morcheeba) singing
The smell of cocoa butter (it makes me think of growing up on the beach)
The feel of velour (just like Zapp Brannigan)
The smell of both old and new books
The feel of the air vent on an airplane (it almost makes up for the cramped seat)
Taking a hot shower
The feel of a plush lawn under my feet
Being bitten on the neck (I can thank my last, and only, girlfriend for discovering that about myself...sorry if that's TMI)
The sound of a woman purring or rolling an "r" (oh, that's nice)
I'll stop there...I could keep going, though.
