That’s easy. When it comes to anal sex there is no better lube than Boy Butter. It’s a lube that is specifically made for anal excursions.
For anal play, you want a lube that’s thick and stays in place. Water, silicone, oil, and petroleum based lubes have properties that are good but none really hit the spot. Boy Butter is quite unique because it combines oil (coconut oil) and silicone into a creamy lube that does (almost) everything you need. Plus, unlike all other silicone based lubes, it washes of with just some soap and water.
Both of Boy Butter’s ingredients are not condom safe, so keep that in mind. The website claims that it is safe for all toys, but I have yet to try it on silicone so I can’t confirm or deny. I’m inclined to believe them. I suppose that someone would have called them on it by now if they were lying. This is lube is definitely not for vaginal sex. The oils can irritate the vagina.
All those issues are addressed by their recent release of a water based version of their original product. It’s comically called; You'll Never Know It Isn't Boy Butter. I have yet to try it out but I hear it’s almost as good. If their advertising is to be believed, You'll Never Know It Isn't Boy Butter.
I know this sounds a bit like a paid advert but trust me, it’s not. (I wish it was!) I just really like their products.
