Well, I've had both, Nine and nineteen and, providing She and/or she have taken a shower, even if turned on, the "sweat" produced has little or no taste nor smell. The Nine never "sweated" but, rather obviously, She had gotten turned on.

Often, you will see dogs who become very interested in upskirts. Dogs think with their noses. If you've ever handled fried chicken and then introduced yourself to a dog (with a functioning nose) you'll notice him intently studying your hands. It gets even funnier if you slipped a bit in the washroom. I'll explain a bit what's actually going on:

If you walk into a restaurant (serving a wide variety of foods), you normally will only be able to identify one item. Your nose and brain team can only handle one, maybe two, things at a time. With dogs, though, it's different.

Dogs' noses are so sensitive, that in that same restaurant, if the dog could write out the list, he could tell you every single thing that was cooked and served PLUS the chemical identity of everyone on that restaurant and whether or not they are smokers, drunk, passing gas, or have had sex in the past few days.

Think of the recent news in Toronto. Some stupid kid robbed a (bank? store? something) the other day. The cops showed up with their K9 unit (a cop and a trained dog.) The dog followed the footsteps of the stupid kid by smelling the difference in rubber on the pavement. The dog could identify which shoe had recently walked by, even if there were hundreds of people walking by. Cops used these dogs. Rescue squads use them to help find trapped people in rubble after disasters. Drug dogs can smell chemicals even wrapped in 55 gallon plastic drums filled with oil.

So, when you see two dogs greeting each other, they are getting a library full of information about the butts they are sniffing.

And, when they are looking up skirts, they're identifying the girl, her mother, her grandmother, and what the girl had for lunch three days ago.

I'm sure the "sweat" that a girl produces is quite unique to Her and a dog will be able to judge just how great Her orgasms usually are for Her.
