Many people consider thongs sexy. Realistically, they are both conduits for germs to spread, causing yeast infections and also they are inelegant.
Doctors and researchers have concluded that thongs, "can cause infections, damage the musculoskeletal system and impact fertility."
Also, "One way a thong might be a culprit of infection is that it can serve as a conduit for bacteria. Since a thong is a continuous and close fitting strip of fabric, it can easily pick up fecal matter and bacteria from the anus, and if the thong moves, can carry that matter forward to the vagina and urinary tract. One gynecologist likened a thong to a subway car transporting bacteria from the rectum to the vagina. UTIs and some types of vaginitis (although not yeast infections) are caused by bacteria, often from fecal matter, which is why thongs could be implicated in some instances of infection."
Thongs were originally inspired by primitive peoples in tribal societies.
Can you imagine Grace Kelly wearing a thong? I thought not. We are supposed to be living in a civilized society, and therefore, should act, and dress, accordingly.
Why not instead use a nice lacy cotton panty? Not only is this elegant and comfortable but it is also more hygenic than thongs. And, having your thong or any kind of underwear show is in very poor taste.
