"Few men possess sufficient flexibility and penis length to safely perform the necessary frontbend.[1] 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 Bartle and 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.[8]"
Volgens mij is het safe to say dat je al die tijd die je verspilt aan oefenen beter kunt besteden aan het vinden van een vriendin.
