I agree with lantiseptic. Has gotten me through a lot of rides. I carry 3 levels of saddle sore protection. First is chamois cream. But you don't want to use that if you already have sores. Next up is bag balm (for cows), which is pretty much just lanolin. Then I have lantiseptic. Just carrying chamois cream would probably work if I would use it at the first sign of trouble, but that's not how I usually do things. I'm probably okay without anything right now, unless it rains.
