Of course, I do clean my ass so "the movement of the thong when i walk" per the stated article is not passing bacteria from the back to the front. I also wear a thong that fits and isn't sliding around. Perhaps if your are prone to infections or sloppy on cleanliness an thong may increase your chance of infection, but neither I or any of my friends have had this problem.
