WOMEN & GIRLS: Why wear Thong Underwear and/or Swimwear?
I'm seeking serious answers from those with firsthand experience, not a "well they must be..." or "I would never..." or the like. To assist with demographic classification, also please include age or age range in answers.
(MEN & BOYS: See my other question on the same topic.)
