Autofellatio

[Tina]

Autofellatio is the act of oral stimulation of ones own penis as a form of masturbation. While few human males are sufficiently well-endowed and/or flexible enough to perform the frontbend required, increased flexibility achieved via gravity-assisted positions, and physical training such as gymnastics, contortion or yoga may make it possible for some. Fewer than 1% of men can successfully suck or lick their own penises.

The [hermetic] profession of sucking ones own penis.

Nobody in the history of man has reported being able to perform this almost mystical feat because the few percentage of the world population who actually can perform [autofellatio] never leave their houses. However diaries and memoirs have been found, [post-mortem].
