Yes, we've used it. Good fun with PVC waterproof bed sheets - you need very little of it for a very slippery sex session. However, absolute pain in the ass to clean up. It is water soluble, so it eventually washes away and won't block drains, but it takes a lot of water and time to get rid of it, especially out of your hair, towels, or any fabrics. It is also very slippery if it is on the floor of a shower. We still have 75% of a packet on a shelf as we just can't be bothered with the clean-up again! To conclude - worth it for a "I'll try everything once" thing, but otherwise baby oil is better for routine slippery sex.
