While I have not specifically used an anal lube, I would suggest checking out the reviews on some of them. anal lubes on ef
if you click that link you can over look some of the anal lubes EF offers, click on one you like, scroll down and read all the reviews. I always read at least 3 reviews on a product before buying, the lowest rating review, and the highest rating and most recent. Then I pick one at random, or read more than 3. I like to get a lot of opinions on the product to better determine how I would like the product.
