[NSFW] How many guys would really suck their own penis if they were limber enough to do it?

Years ago a friend of mine had an adult book and in it was an article telling men how they could practice to become limber enough to give themselves a blow job. I was thinking why?? Why would any man want to give himself a blow job if he can get a woman to do it? I don’t care if I was as bendy as Gumby that is a thought that would never come to my head. And I would be surprised if any guy here would go on record to say he would if he could.
