Butt wait, better yet, buy a tube of -Butt'r- by Paceline its a skin lubricant & chamois Cream (actual name) great stuff, but need to use pre-ride, not post ride. Post Ride I use polysporin. BTW- I agree with Louis, if'n its that bad you have something else going on. I was there once and found that the laundry soap was a problem. Started washing in baking powder and drying in air helped. (not my Butt, the clothes)
