Question from a newbie here - could it potentially be related to blockage of the fecal kind? Had a humbling experience several months ago where I got too cocky attempting to take on a 10.5x8 dick because the previous 9x6.5 the weekend before felt good. Not only did it hurt like hell, but once he was in, he hit a snag past the second hole (and had no idea what that meant then), so I learned to clean through the second hole when I meet with a provider. If you do not think that is the reason, then I do not know.
