You could put this gel pretty much anywhere that isn't inside your body. My favorite applications are on the clit and around the anus – it certainly makes you squirm in a really good way! However, given that it states it is "not a personal lubricant" in the fine print, I would stay away from putting it inside your body.

This gel is slick, but thick. A pea-sized drop on my finger slides a little, but doesn't separate no matter what direction gravity is pulling from. However, it is not to the point that it drags. It's actually one of the least messy lubes that I've encountered. Once applied, it stays where it's supposed to be, especially if you rub it in, and feels very smooth and velvety. It's translucent but not completely clear, and leaves a very thin smooth film/residue on my fingers for a while after touching it (the sensation reminds me a little of a high-end soap that's supposed to make your skin smooth, but it's still kind of weird).

This lube has a light and pleasant minty smell, and a slightly soapy taste. This wouldn't be a big deal for me normally, but it also tingles sharply on the tongue a LOT, so be prepared for that if you're going down on a person who has applied it in the past hour.

The "tingling sensation" is a bit of an exaggeration. For me, it certainly produced a very obvious and very pleasant warm feeling comparable to having warm oil poured on you – not particularly intense, but definitely attention-grabbing. On average, it lasted for about fifteen to twenty minutes, with most of the sensation concentrated in the first five. It was shorter and less intense if the spots where it was applied were exposed to open air with no stimulation, longer and more intense if the gel was rubbed in thoroughly or I was pressing my legs together.
After a while, it kind of just absorbs into the body and there is no clean up necessary (unless you feel like it).
Now, I'm going to make a caveat saying that I'm probably less sensitive than most people I've talked with about it, and no doubt the effect will be largely dependent on the person. However, while it's a perfectly decent product, it didn't really live up to the expectations I had for it.
