It is the most beautiful of all the existant arts existing in this world; hell, in the universe for this sake. While most, if not all, people can do it, only some have actually mastered and have movies at their name because of this. There are many ways to do this, and they all depend on how is your mind and genitals (including ass) doing. Called vulgarly as masturbation.
I have mastered the art of fucking yourself.
