I gotta tell ya, what prompted this thread was my shopping expedition with my Perfect Child[sup]TM[/sup] yesterday. As we wandered thru the lingerie department, there was much touching of undergarments. No, we’re not that weird - but some of the fabrics were. Plus if you’re going to wear something right against your skin, you need to know that it won’t feel irritating.
Anyway, while I did not buy the teeny-tiny little thongs, if I ever did, I’d have to wash 'em, lest I imagine all the grubby fingers that had caressed them as they hung on the rack. And lest some of you get wound up in weird fantasies about me and my undergarments, I prefer plain white cotton grannie-panties that come in hermetically sealed packages… So much for the caress factor.
