30 days? It’s been so much longer than that. I switched over to daily thing wear two decades ago or longer. The last time I was not sporting a thong on my body was a year and a half ago when I had major surgery. Then it was nothing at all for a few weeks except shorts and t-shirt. For me when I get up in the morning and I open my top drawer, it’s a choice of thongs, a few G-strings, and a couple more erotic pieces for play.
