I recently found 2 pair old old jockey bikinis from before my first circumcision. They still fit me, although sugly. Was strange to put them on and to think the last time I had worn those, I was still with long foreksin. They would be at least 25 years old. Had stopped wearing them when I found a better style.
Right now, I have my "fleet" of calvin sport briefs that are no longer made. They are still in good condition. Calvin has no replacement, so by the time these wear out, I'll have to hunt for new brand (unless Calvin re-introduces that style (string bikini).
