The thing about lubricants, is that pretty much everyone uses them, but they don’t give a whole lot of thought as to what’s in them. Lubricants are a big business, because no one wants to have dry sex. Really, may as well not HAVE sex at that point. Commercially, you have a fair amount of options, ranging from whatever liquid nastiness they can cram into a bottle, to silicone, to that gold standard, gynecologist recommended KY© Brand Jelly. (Which really only increases my general contempt of gynecologists.)
