I've got one hand in my pocket and the other's...

If I rub it will a genie appear?

No, this is not in Vegas at the Annual Adult Industry convention. This is in Japan. This is part of the penis festival which takes place every year.  The Honen Matsuri takes place in Komaki city.  Tons of people of all ages and backgrounds gather to watch a giant wooden penis being carried.  Even the Shinto priests walking along have these hats that kind of remind me of a phallic symbol.  The festival has tons of food stands which all try to cater to the celebration of fertility.  Dipped chocolate bananas with marshmallow heads, phallus shaped candy, cookies, etc, etc.

There is also a festival dedicated to the women's southern region but I have not yet been to that one.  The festival which sounds odd is actually quite fun. It's not just a bunch of perverts getting drunk. In fact, the female to male ratio might be higher.  It is a good time where one can enjoy drinking, eating delicious food, meeting happy and friendly people alongside giant wooden male parts.  And women often rub the testicle region when trying to conceive.  Only in Japan...
