Jockstrap

The first time I ever put on a jockstrap I had no idea on what they meant with size.
I thought it went by dick size , so when they asked me what size I wore of course like any guy I said the longest and biggest number.
J. and his than partner A. had a good life about this as we walked through the Big Five Sporting Goods.
He slipped his hands around my waist and said in a scruffy voice ," he wears a size large , maybe medium?".
This was my first day with two, horny older men  and boy did  I have that sinking  feeling like I was failing at it.
That was over two years ago.. Now I own a wide vast collection of them. Vintage jocks , new age jocks , fancy jocks , fetish jocks ,leather jocks , red jocks , blue jocks , smelly jocks and even a Wal-Mart jock.
I guess I know who to blame for my underwear fetish.
