Call this lack of common sense or not (ha-ha-ha) but I have been running for a number of months and suffer from chafing in places that are just not comfortable afterwards. Too embarassed to ask others if it happens to them, I have just been dealing with the pain. I just recently shared this with my wife, who after about 5 minutes of laughing so hard, she suggested I use some petroleum jelly or our 10 month old son's vaseline on those tender places. I have yet to try this but I am most certain it will work. If so, I will definitely suggest this to new runners. I'm sure it's written somewhere, I just never new.
