I don’t mind cotton panties especially when I go down south were it is hot and humid. Micro fiber is also nice to wear down there. I wear silk and nylon too but it makes me sweat down there sometimes when I’m down south. Besides growing up most of the panties I tried on were cotton, I did like the feel of the silk and nylon panties too. My actual first pair of panties I tried on were silk, my little duck love the feel of the material rubbing against it. I guess it doesn’t matter if they’re cotton or other wise, just as long as they are panties.
