Smells: what are your favorite when it comes to sex?

My olfactory sense is probably my second most important when it comes to sex, so certain smells can really turn me on.

I'm a top, so I love to sniff a soft pair of feet while my bottom is on his back or a clean-yet-musky ass as I eat him out. And of course, pits are my favorite. I also respond to some light cologne, especially if I'm flirting with a boy out in public.

What about you all? Any smells really turn you on?
