Lubes

Lubricant comes in several varieties;

Water-based Lubricant is safe for the body and does not stain. Only water-based lubes should be used with silicone toys.

Silicone Lubricant is great for stroking and foreplay. It can stain but is water-resistant for shower fun.

Oil-Based Lubricants are great but are NOT latex condom compatible and should be kept away from latex clothing. 

Thick formulas are best for anal lubrication.
