Well...don't such people, today, generally wear loincloths or diapers or skivvies, or something that gives some support (and protection against scissoring?) I thought that pretty much every culture had male genital veiling of some sort, even to the most minimal degree of penis-sheaths.
(I recently read an account of De Anza's expedition through the desert near modern El Centro, California, and he said the men went absolutely naked. This surprised me, as I had thought all native Americans had at very least a loincloth for costume.)
Valid point, though, as for the earliest of all humans, those who were too primitive even to build a crotch-strap or nut-sling.
