The annual 'Big Dick' festival held in Kawasaki, Japan, is proof that Japanese men need to build massive model 'dicks' because they are too ashamed to expose their own miniature versions!
Starting with India, and travelling eastwards, Asian men tend be not blessed with 'tools' as large as their African brethren because nature being what it is, imperfect, decided that having 'big dicks' in Africa, which resembled elephant trunks, would protect them from extinction! Whereby in Asia, nature multiplied humans in millions because the climate was more suitable, and huge 'dicks' were not necessary for reproduction because rabbits don't possess them either!
Japan has decided to commemorate the coming of spring in the form of a phallic festival giving Japanese women annually the chance to see what they have missed if their hubbies would have been African. After the festival is over, an annual holiday exodus of Japanese women occurs heading for Africa hoping to see the 'real bigger picture!'
Meanwhile, Asian men, continue to maintain their massive success in avoiding extinction and allowing Asian peoples to multiply like rabbits because as one sex-specialist has discovered; "it is not the size that counts, it is how it tastes, and the Kamasutra was written in India anyway!"
Thus proving what the sex-specialist confirmed; 'taste is everything' and a substantial amount of positional fantasy, which is virtually impossible to achieve in darkest Africa and the Sahara (damn sand under foreskin, OUCH!). Hence, nature gave African males huge 'dicks' instead of huge grey matter as a matter of survival!
