That fewer than 1% of males can successfully orally contact their own penis

Physical aspects 
Few men possess sufficient flexibility and 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. American biologists Craig Bartleand Alfred Charles Kinsey reported that fewer than 1% of males can successfully orally contact their own penis and that only 2 or 3 men in a thousand could perform a full autofellatio. Previously, autofellatio was considered by behavioristic science a problem rather than as a variety in sexual practice.
