My concern with lubes would be that some start to feel tacky after a while. Yuck! In previous threads about chamois cream others have mentioned using diaper rash cream in place of the chamois butter because they were sensitive to the ingredients in various chamois creams. You might give that a try. Aveeno makes one that is a lighter texture and washes out easily.
