Autofellatio

Few men possess sufficient flexibility and/or penis length to safely perform the necessary frontbend. However, increased flexibility achieved via gravity-assisted positions, and physical training such as gymnastics, contortion, or yoga may make it possible for some.[citation needed] American biologist Craig Bartle and Alfred Charles Kinsey reported that fewer than 1% of men can successfully orally contact their own penis. Previously, autofellatio was considered by behavioristic science a problem rather than as a variety in sexual practice.
