It works well for masturbating each other (separately or at the same time). It's great for a quickie and makes a fun mood enhancer, as long as you don't tend to take an hour for every little detail. It can be fun with toys, not a good one if you intend on doing oral.

It's very slick at first and not super thick like most K-y products. It does tend to get sticky after extended play, a half hour of rubbing is about all you'll get out of it. Re-applying it will bring the slick feeling back. It comes out of the bottle fast at room temperature, so be careful of that.

It doesn't have an over powering smell that I noticed, but the feeling alone was enough to tell me I shouldn't put it in my mouth.

It lasted for about half an hour of mutual masturbation. So I'm guessing it would be the same for masturbating alone. Re-applying it every half hour or so isn't so bad. It's water based, so a warm wet cloth is usually enough to wipe it off. I liked the sensations it provided but the stickiness after a time was a bit disheartening.

I bought it a while back and the plastic box it came in was attractive. It was a pain to get open but it was worth the 3 minutes of trouble. The tubes don't stand alone so if you don't put them in the little plastic loops you get you might lose one. They are suitable for travel, as I have never had any leakage problems in our travels. They have a snap-push button top where you push down on one side and the other snaps up, making it easy to open and close one-handed. Would make a nice gift for pretty much anyone.

The Yours warming sensation takes a minute, but with some mildly vigorous activity it get's pretty hot. The Mine has a cooling/tingling sensation that feels really nice, it takes a little rubbing in to get it going but once it goes it's good. When you use them separately (like foreplay with mutual masturbation) it's a nice way to warm up. If you follow that up with sex, the two together provide this unusual warming/cooling cycle which is actually quite pleasant.

I like the Yours and Mine, it's fun for some nice foreplay and romantic sex. I'm not sure how well it would work in other circumstances because that's all I use it for.

We enjoyed it immensely, it had some mild issues but it is fun to use for a specific purpose.
