I'm not judging in any way, but just interested in reading why you like to do it. I have seen pics of guys who have been plowed so much, that their holes look like tunnels. Why is it that you like to bottom? Does it become easier or more difficult to release waste? Is it possible for a large hole to close again? For those that love to have a big dick up their ass, what's the largest one (length & girth) that you have consumed?
