These nine things are:
1. Your walk. Confident in heels, or sultry and hip-swinging, pretty much anything but a manly clomp. Wonder how they feel about what I normally got going on - the panties-riding-up wiggle.

2. Your voice. I'm assuming the baby talk voice is a big turn off, but anything else gets a thumbs up.

3. Your sharp wit. Alden writes, "Just watch any classic screwball comedy - verbal sparring is the ultimate foreplay."

4. The way you dance. Even if you're not dirty dancing, dancing of any kind is certainly suggestive and, if you're good at it, a major turn-on.

5. Your adventurous spirit. Being game implies that you might be willing to be just as adventurous without your clothes on.

6. Your shyness. Guys get a charge out of, as Ludacris says, "A lady in the street, but a freak in the bed."

7. Your laugh. Alden reminisces, "I think the laugh was the first thing I ever found sexy. Before I knew what sexy was, I remember hearing Kathleen Turner's laugh (I was probably 7) and feeling something ... different."

8. The way you smell. This is not about your coconut shampoo or your Beyonce perfume, this is about the inherent YOU smell. Probably comes from a deep evolutionary/chemical place that we don't have room to explore here.

9. Your ability to communicate. After all, you have to eventually put your clothes back on and look each other in the eye and connect over something else other than that you both enjoy those fuzzy handcuffs.
