You don't have to go to a cycling specific store or get cycling specific cream if you want some chamois lube. Your local pharmacy will have options.

Lots of people use udder cream - Udderly Smooth is popular on my team (its not greasy), My husband likes Bag Balm - but it has a petroleum jelly base, so its kind of goopy and hard to clean out of shorts. I don't use much chamois cream, but I like plain old zinc oxide cream when I do. There's another current thread that mentions a powder, with the colorful name of Anti-Monkey Butt powder... but it actually sounds like something I might want to give a try, as I don't like creams too much.
