Pjur is well-known in Europe—a little less so in the States—but its Backdoor Silicone Lubricant is by far one of the best lubes for anal sex.
The Wet Uranus Anal Silicone Lube was created especially with anal in mind. This lube is a thick silicone-based lube which ensures for safe and comfortable use during anal sex. Being a silicone lube, this lube will keep lubricating for quite some time when other lubes may give in and require a new application.
Man, does the brand know how to market and package a good product. Boy Butter, which resembles an actual tub of margarine, blends coconut oil and organic silicone for an anal-sex lube you can trust.
"Silicone can degrade silicone toys, so if you're using silicone toys, you need to stick with a high-quality water-based lube, like pjur AQUA," says Engle. (See more: What Are Anal Beads And How Do You Use Them?)
This water-based lube is specifically designed for anal, and is one of the best sellers on Lovehoney's site. It's safe to use for all condoms and toys, including silicone.

Place a drop or two of your chosen silicone lube on the toy and wait a few minutes. If the lube stays slick and, well, lube like, you are good to go. If it begins to gum up and you have to scrape at it to get it off, don’t use that lube with that toy. You can always use a good water base / silicone hybrid lube like Sliquid Silk if you want to be on the safe side.
(Note: Silicone lubricants are safe for humans, but they can damage some types of sex toys over time. If you plan to use your lube on sex toys, look for ones labeled "safe for sex toys.")
