Many women who have never worn a thong seem to have a lot of myths about them.  Madeline in Illinois asks, "Are thongs bad for your health?"

Absolutely no, otherwise we would have millions of unhealthy men and women out there.  However, the design of a thong is such that for women who do not believe in clean underwear, they can create problems. 

So our advice is that no matter what you wear, change your advice daily (at a minimum).  In other words, wear something clean in the morning and take it off in the evening when you go to bed (no need to wear underwear in bed).  If you do wear underwear to bed, you must put on something clean.  Then it doesn't matter whether you wear thongs or G-strings.
