Autofellatio
Autofellatio is a sex act wherein a male performs oral sex on himself; a form of masturbation. This is usually not possible for most men, but is possible in the case of sufficient flexibility or endowment. Gymnastics and/or yoga are potential methods by which one may increase one's flexibility, which might enable one to achieve such a capability.
Autofellatio has been featured in a few pornographic movies, although it is not one of the more popular subjects. Some sex actors have expressed contempt for men who autofellate.
In Egyptian mythology, the god Atum (Ra) created the gods Shu and Tefnut by autofellatio; or at least, it is argued that a proper translation of certain texts demonstrate that the ancient Egyptians believed this. Other translations ascribe this creation to mucus, rather than semen. It has also been argued that the Ouroboros is a symbol of autofellatio.
Autocunnilingus for a woman is possible, but would be more difficult to perform since her head must move a greater distance.
