Well, it does make your cockstrom look bigger. But seriously, it's a jungle down there otherwise.
I'd be more concerned about circumcision, if you want to question social mores, since it's a much more permanent and painful cut than the surrounding hair.
Circumcision is something people do for either religious or medical reason, it has a long history behind it. It may be useless but at least it is not invented yesterday by the chemical or porn industry.
For the "jungle down", I think shaving it make boys and girls look like prepubescent kids, or some kid of caricature of kids. When I said weird I meant it because presence of pubic hair has been for a long time the marker of the beginning of sexual life.
I guess I didn't realize you were talking about scorched-earth-policy shaving rather than regular trimming. I agree that shaving it completely is unappealing, but I was not aware of that being common or trendy. Maybe some of them are doing it for medical reasons as well... ; )
