Mango Butter?

Well, I tried it. It seemed to work very well.

Process was, I put about half a teaspoon of coconut oil, about a quarter of that amount (8th of a teaspoon) each of the mango and shea butters, into a shot glass, and put that in the middle of a teacup of hot water from the microwave, gave it a few minutes. The mango butter is very grainy cold, so not sure it would be a good idea to try to get it up inside cold.

While it was melting, I did a quick internal cleaning, By the time I was done, the lube was ready. Although grainy cold, the mango butter was smooth and slippery when melted. I filled my syringe (the one offered for sale here on the website), lubricated the hole and rectum, and then lubricated the Vice and slid it in. It was in for a little over 2 hours, and kept the slickness. After removal, my hole felt great. If time permitted, I could have gone on longer. I think it's a very healthy lube option.

Interestingly, though each of the ingredients were solid before melting, the three oils stayed in liquid form after cooling back down. Might be able to make a small bottle of this stuff, so I don't have to make a micro batch every time...
