When I first started taking enemas, I could easily take about 3 quarts of water (one and a half bags). Since then, I've gotten very advanced into anal play and can take a 12" or longer object straight up with no problem. (Basically, my lower colon no longer significantly curves... it's essentially straightened itself out.)I've noticed over the last few years that I can no longer take more than a full bag (2 quarts), and sometimes even less than that. (I measure total volume by seeing how much I can take after I clean out all the matter.) My theory is that since my colon is "straightened" out instead of "curving" where the sigmoid would be, the total volume that I can take has shrunk.Is this plausible? Have I traded off one ability for another -- more than one bag in exchange for toy depth?
