Made to be a lubricant with sensations. His is warming, and hers is tingling, then when they "come together" it creates an extra sensation and experience. You can use as much or little as you like of either one your own preference. Plus it's safe to use with latex condoms.

Personally, my husband and I didn't care for this. The consistency is real smooth, but after you apply them, they become real sticky and seem to "wear off" quickly, so you have to keep reapplying.
After that, during sex it got a real thick feeling on us and just was not pleasurable at all.

They smell good. Not the usual "lube" smell. Since its a lubricant, we didn't feel the need to put it in our mouth!

Since we didn't enjoy this, I don't know how long it would have lasted. It washes off easily in the shower with soap and water. Out of the bottle its very runny. After a few minutes of massaging and rubbing it into certain areas, it gets very thick and goes away. The more you add the thicker it gets and very, very sticky. Have a washcloth near by!
