an undergarment similar to a thong but has a thinner piece of fabric that lays between the butt cheeks. Whereas a thong has a slightly triangular shaped piece of fabric in the back with a width ranging from about 1 centimeter to 3 centimeters, a g-string has a very, very narrow rectangular shaped back fabric piece about half a centimeter wide. Both garments are approximately the same length in the back. The front of the g-string is similar to the front of the bikini underwear, except usually a good deal more skimpy. ***The g-string does *not*, I repeat does NOT stimulate the g-spot or clitoris in any manner, because the "string" part is in the back not the front or the inside where those areas are.***
Women buy g-strings because a g-string is useful to avoid panty lines when wearing thin and/or low-rise pants, and because some people like the look of g-strings, not because g-strings are stimulating to the wearer(They aren't.)
