I agree, it is a bit ridiculous, but the vast majority of men are probably in favor of the ban. Guys with small penises, average penises and even large penises that are growers don't necessarily want to see some hung shower parading around in a speedo, unless they are LP aficionados. And while women may like it, those with kids in tow may not.
Last line of the article:
"We are also looking into offering complimentary male waxing, which will ensure preserve the dignity of all our guests."
So having body hair is undignified???
