I’ve posted about this elsewhere here I think; growing up playing sports in the late 80s and 90s jockstraps/athletic supporters were pretty common. Part of our PE class uniform if you can believe that, but so we’re shitty short shorts and coarse gray t-shirts. We also had communal showers.
The right jock, for me at least, can be more comfortable than compression shorts. But not always the right choice…like leg presses unless you want everyone to see it all.
jocks are far less common from my experience but are making a bit of a come back. Personally I’m not a big fan of some of the fashion jocks, but I won’t knock anyone for wearing them.
