She decided that she want to be a "normal" bottom so she is worn as often as possible, but the biggest question was should she be panties for a women or boxershorts for a man.
She thought long about it and finally decided to become panties out of several reasons: First she always asked herself how when she put on hers how it would be like to be one, secondly and most importantly panties are cut to fit thight around a womans body and she wanted it so around 100% of her is used not as would happen as a boxer short that most of her will be unused and thirdly she knows from her own expirence that interesting things can happen down there with a women.
