K-Y yours and mine is a set of two complimentary lubricants which, when mixed together, are supposed to create a sensory explosion. The lubricants come in two separate test-tube-shaped containers: one blue and one purple. The blue test tube is labeled yours, for him, and the purple test tube is labeled mine, for her. Personally, I feel that it would have been better if they had simply left it at yours and mine without specifying which gender gets which, however the labeling has no bearing on my enjoyment of the product.

The lubricant in the blue, yours bottle causes a slight warming effect, and the lubricant in the purple, mine bottle a cooling effect. Although marketed for use together, the two lubricants are perfectly functional when used individually. Although marked for him and for her, it really doesn't matter who starts off with which. When combined however, the feelings caused by the lubricants do increase and combine into an unusual icy-hot kind of sensation. My boyfriend really enjoys this sensation, but I tend to go back and forth on how I feel about it. Most of the time I find the strange sensations caused by the combined lubes to be a distraction and create a kind of numbing effect, making it more difficult for me to get off or enjoy the sensations.

Regardless of how I’m feeling about using K-Y yours and mine on any given day, both my boyfriend and I can always agree on a few things. This lubricant is thin and drippy so be careful when you pour, but we've never had a problem with it drying out for us. Of course, that my be because my natural lubrication is taking over. And although the test tube containers are very cute, they are not very good containers as they are prone to leaking and have no base on which to stand up in order to prevent leaking.
