The photos of wrestlers show young guys in their late teens/early twenties in lycra singlets, some with underwear, some with jocks, but most with nothing under a single layer of lycra.
They roll about the floor in close contact and then stand up, aroused, clearly pointing in all directions, leaving nothing to the imagination!
American football kit and cycling skin suits are similar.
I find it confusing that this is acceptable to the guys wrestling and the spectators, but there is still an abhorrence of guys wearing speedos that are normally double lined and tight enough to hold `things` in place.
