If you are visiting Bali for the first time in your life you might be surprised by people having a nap on the street during daytime or street vendors pursuing you all the way from the temples outside of the city to downtown just because they want to sell you a penis-shaped can opener. Anyway, do not get stressed, they are just doing their business and do not want to harm you or do anything to you with that thing although it looks kind of horny if a female offers it to you...
Those things you see on the pictures are simply symbol of fertility that exists since ancient times all over the world.
The representation of the male genitals is also believed to bring you good luck. It stands as an attribute of the supreme God for the local Hinduists called Shiva Linga.
In the past men used to wear the penis charms as a necklace, convinced that it protects them from evil spirits. Nowadays they are used for decoration for all kinds of useful tools such as keyhangers, kitchen utensils and so on.
