cleo is right, the initial frisson of going commando can taper off. if she's really turned on at first maybe she should try some tampons.
she has to decide how she wants to feel herself. i think of myself as a very sexual woman and don't want to really lose my sexy frame of mind but i also usualy don't want a wet spot showing on the back of my skirt. lol i've been going pantyless for years but i still enjoy the thrill of stepping out in a sundress on a warm breezy day, wearing nothing but me underneath, and relishing the feminine almost-naked feeling. it makes me feel like a sex goddess.
