Q: Is there any way to prevent chafing?

Km: Yes. Body Glide. Seriously. People should buy stock in this company before the summer hits. Vaseline works in a pinch, and there are some other ways people have prevented chafing, but Body Glide is the best.

Chafing

Owwww... although there is a lot of stuff you can do to help prevent chafing (like apply body glide, vaseline, or baby powder to "chafe-prone" areas), inevitably you miss something. So, then what? First, wash the area with soap and cold water and apply some type of anti-bacterial ointment. Covering the affected area with a band-aid or gauze can also help protect it, and wearing loose-fitting clothing also helps. Some people also recommend using diaper rash ointment.
