Admittedly I don't have near as big a cock as ya'll and my husband only puts his balls in my purse. Having said that, I've NEVER seen a dewd actually utilize that hole in the drawers. They just unzip their flies and push down the underooz to get at the winkie.
In Europe (if I do recollect properly) there is no "winkie slit" for the menz.
I remember asking one/few fellas here in the states, "Ummm whyfor you don't use the winkie slit if it was put there (I would think) because it serves a usefull purpose."

The answer was always something akin to, "It's a literal pain to do it that way. Just push the drawers down and be done. You gotta shake that stuff up after yer done anyway."
Ummmmmmm ok.
Dewds are wierd.
I'm glad I have a nani.
