last time i was able to sort them all out, about a year ago, i had around 475 panties, including the ones that are part of a set with a bra and/or a garter belt & stockings - and i've gotten a few more since then. so i could go about 16 months or so & wear a different pair every day, without ever having to wear one twice, LOL!
of course, i've been adding panties to my collection for about 14 or 15 years now, & most of them i've bought on sale, either locally or online; the overwhelming majority of them ate either low-rise thongs, g-strings (my favorite, since i'm a total SLUT LOL!), or skimpy low-rise bikinis. i haven't worn male underwear in about all of the time since i began getting panties - they are so much more comfortable & WAY more sexy, too - which really turns me on hehehehehehe...
