I have always been in awe of those extremely talented individuals who have managed to get it right so that they can suck and fuck themselves! Clearly the endowment has to be sufficient, to reach certain hard to get at parts of the anatomy, but a certain gymnastic ability is mandatory! It amazes me, that given the huge number of well-endowed guys on this and other sites, one rarely sees evidence of such feats! I challenge all guys with this rare combination of talent to attempt such feats (I know I can't) and then post the evidence on this site for all to admire! The ability to control sexual pleasure must be the ultimate in self gratification! Good luck to all who take up the challenge!
