I ran out of underwear this week, even though I have over 40 jocks.
I have a jock fetish.
When I see an ad for jocks, I find it hard to resist the temptation to buy a new one. I love how a jock hugs my ass and also the feeling of my naked ass rubbing against my shorts/jeans.
While hiking or working out, a jock is a much better choice than "normal" underwear.
