Positions is really hard for me to determine. I have pooped in just about every position possible. I have done it walking my dog, out shopping. sitting in the park laying out on the grass during a picnic. I have done it riding a bike. I highly recommend the bike riding for those that are into it for the sexual reasons. I have done it leaning on a shopping cart while out in the market. One of my favorites is laying on my belly reading a book in bed and spreading my legs and letting it just fill my diaper and give a few squirts of pee to get the diaper a little mushy so I can get that tingling feeling in my belly. There are so many ways to really enjoy pooping. Just try all different ways and see which one makes you feel the best. Believe me it is so much fun doing the learning process. Enjoy it and poop to your hearts content.
I started at a very young age. to be honest I was about eleven years old. I loved the feeling of holding it in until it was time to go home. I was maybe 5 blocks from school and had my choice of walking or taking the bus. I would have my back pack on and made sure my panties wear a bit tight. I would wait at the light until the crossing guard told us it was okay to cross and give a little push to get the poop moving into my panties. As soon as I got across the street there was a candy store and i would go inside and see what I was in the mood for, and push the rest of the poop out into my panties. I would hold it in sometimes for two days to make sure it was a huge poop. I get my candy and leave the store. I just loved the way it squished all over my butt and private. I would walk home just to enhance the feeling and it made me very excited. (I was an early bloomer). I would go home to my tree house and hang out there and squish it around and it was a feeling that is hard to describe to someone that has never done it. I didn't mind the clean up, but I was really staining my panties and I was worried my mom might see the stains. At the age of twelve I did baby sitting for a few neighbors, and had easy access to diapers which was like home run !! Now I don't have to mess up my panties and I could just wear my panties right over the diapers. I was like wow now I can pee in the diaper and poop and no one will ever know. I was never into the ab part of the diaper scene, but I loved diapers and I loved the thrill it gave me. I was the little innocent girl with a poop and pee filled diaper that enjoyed the feeling it gave me and the tingling I felt inside when I did my deed. That would be why I am still a diaper lover for over forty years and still feeling the same tingling in my belly when I am naughty. I hope I give you all a little incentive on the life of a diaper lover.
