I find it just a little odd that some guys with supposedly big dick n balls here and females would find it odd to want to wear a used jockstrap. If anyone HAD real balls here, big or not, and actually worked out in a gym. You would understand the need for it. I'd say 90% of truly hung men would want some sort of support, jock or compression or whatever. Hell, I am not hung but still dont like my nuts jangling around when running or doing leg presses. (If you never have seriously worked out you are excused for not understanding) Once I got pinched doing double sided dumbell raises for my shoulder, they came down and crushed my head (yes the small one) I was bruised for weeks if not months. So now I ALWAYS wear a jock and usually another tights over that under my baggies, everything is really snug in place when working out.
Cant say much about females working out, but I guess a really big breasted woman running or bouncing on the eliptical would have the same thing if not wearing a sport bra or bra at all. ????? cant help us gay guys love to work out and the smell of sweat is a turn on, especially jockstrap smell.
