I have not been to Japan, but it is definitely on my to do list! I include only because the most popular blog post I have ever done is about Japan.
It seems people the world over like penises. And they are back in fashion. Apparently at the 2015 Paris Fashion Week designer Rick Owens decided guys should let it all hang out: if gals can flaunt their boobs, why not? Actually it does provide a natural air conditioning, probably helps eliminate jock itch and makes peeing a whole lot easier.
Memo: If you haven’t got it, don’t flaunt it. Besides, forget about the hole in the crotch, who’d wear this thing anyway and why?
