Japan's Male Genital Day! [PICS]

This kind of celebration is celebrated only in Japan! :p
Every year the Japanese celebrate the feast of "Male Genital" in the city of Kawasaki, south of Tokyo. The ceremony was attended by more than 30,000 people and they pray to god with invoking the protection from Sexual Transmitted Diseases (STD) through sexual intercourse.

The ceremony is weird, isn't it? What a nonsense.
