I can tell you what made me STOP going commando! I was having some really bad lower back pain and called up my chiropractor that I hadn't seen for a few years to see if I could make an appointment to come in. Oddly, they told me to come on in that day. I was wearing a dress and no underwear. When the chiro told me that he could do an adjustment that day, I was forced to tell him my situation. So embarrassing. He said, "I'll get a towel. We'll keep things modest." Words I'll never forget.
