The act of a person performing oral sex on their own penis. Like masturbation, it is a solo form of sexual pleasure that needs no partner, though some people also do it as a fetish performance for others to watch.
Interest in autofellatio may be more common among gay men, where it can be seen as a form of self-worship and a display of body confidence. Actually doing it is rare, because it depends on a combination of unusual flexibility and anatomy that most people do not have. Kinsey estimated that only a very small fraction of people would be able to manage it.
For those who try, the novelty is a big part of the appeal, and achieving it is often treated as a personal erotic milestone that takes practice to reach. Opinions on how it actually feels are mixed. Some say it feels more like giving oral sex than receiving it, and the awkward position can make it hard to relax or reach orgasm. The act has a long history and appears in Ancient Egyptian and other mythologies.
Safety
The extreme bending involved puts real strain on the neck and back. Muscle strains, sprains and other back or neck injuries are possible, so people who attempt it should never force their body further than it comfortably goes and should stop at any pain.
