It all depends on your personal preferences! I just use a water-based lube, but there are a ton of different choices! Some anal lubes that I'd recommend on Eden are the Titanmen triple duty cream, which goes on creamy and goes to being slick. Another choice is Wicked Jelle, which is quite thick and actually really slippery. You could go classic and get the Anal-ese, which is flavored and has desensitizers. Finally, you could get the Anal lube, which is scented like cherry. It all depends on personal preference and what you want. There's a lot to choose!
