Hiya !!
Somebody mentioned wearing boxers ................. horrible thought.
For most of us the first CD step is wearing panties much of the time (or 24/7 for many of us including me). I suppose it is feasible to get away with wearing some brands that are not too frilly and feminine, without making too strong a statement about your femininity.
So if you haven't come out, what is the best excuse you can give when asked by SO, mother, room-mate, GF, etc., for not having any masculine underpants in your bedside cabinet?
