DH=dear husband. You're not ignorant if you don't know. Most silicone lubes are considered good for anal play, as they last longer than water-based lubes. However, if you are using a silicone toy, a silicone lube will eat it. My favorite lube for pretty much everything is TooTimid lube. http://www.tootimid.com/too-timid-pleasure-gel.html
