Embarrassed about this and it is 100%% true. My life really sucks because of this. Ok, here it goes. I have done this since I was 13 or so and I don't remember how I started, I wish I would never have! I found some kind of pleasure in making myself poop it was convenient for me to poop on my time. I was in dance, tennis, drama club, chorus and many other after school activities and pooping was so annoying. So I guess I figured out how to "make myself go" when I was at home, comfortable. I did this by squatting in front of the toilet and inserting one finger into my anus, this gave me the feeling of having to go, and miraculously, wiggling it around "tricked" my body into helping me trigger the "gotta go" glan and made my muscles easily push and out came the poo and I was relieved.�I continued to do this for the last 14 years, and I am nearly 27 and can't make myself poo any other way.
