Ok, I think I am one of few who can actually suck their dick, not kiss the head, or touch it with their tongue, full fledged sucking, I can fit about 1/2 of it or more into my mouth, and then I go to town, but here is a "word" of caution, I am very flexible, and it helps to have a larger than average penis (mine is about 7.75 inches), so seriously if you can't do it don't try, cuz you'll end up in the hospital, embarrassed as to why you really broke your back.
