scat poop constipation constipated

When I was a kid my sister kept complaining about the smell of my
poops. We shared a room connected to a bathroom.  Being the age I
was. I wanted to be her best friend really bad she was my cool
older sister!  So I started not pooping when I had urges until I
couldn't wait any longer then I would go to the bathroom and let
out as little as possible to stop the urge. At the start I would
generally go a couple days without pooping then I would let out a
little inch or two long ribbon of poop never completely emptying.
After a while my poops got firmer and thicker I remember it being
hard to pinch through them to break off the ends. Also the
frequency of my urges slowed down over time. And my hunger level
dropped way off as well. Until with out even realizing it I had
gotten fully backed up.

I remember I was sitting in class one day and I had the worst
pain in my stomach like something was ripping inside me or being
cut and at the same time uncontrollable constant urges to poop.
If the poop hadn't been so thick and firm i'm sure I would have
filled my pants in front of my friends. When I could sort of
regain my composure and speak I asked to go to the bathroom, I
tried to walk out of the room normally but I was in severe pain.
When I got to the bathroom I still couldn't poop even though my
body was pushing as hard as it could. For 25 mins I sat there
until it was time for my next class, I only had one more class
so I went and sat there in agony with my body almost constantly
involuntarily trying to force the poop out until school was
over.

I lived close enough to the school that I walked or rode my bike.
I didn't want to poop at home because of my sister phobia but I
realized if I didn't poop I would probably need to go to the
hospital. So I went to a park near our house that had a pretty
deep woods. When I had gotten pretty deep and found a fallen
branch to sit on I started to push after a while the log began to
move a little but it was too thick to pass through my anus and I
was beginning to feel like I might tear so with all my might I
squeezed it to make the mass small enough to fit through. It was
so exhausting. For over thirty minutes I pushed out a tiny
amount then squeezed pushed then squeezed. I looked down between
my legs and could see about a 2.5 inch thick dark brown clay
looking mass hanging out of me.

After about 16 inches had been pushed out of me like that my body
had a huge contraction I felt my anus stretch painfully wide for
a fraction of a second then the clay like part ended and a huge
amount of slightly softer poop rushed out of me. This poop was
still quite solid but not so much so that my anus was being torn
by it. I'd guess another 16 to 24 inches of poop came out of me
in about 1 second.

I felt extreme relief at this point but I felt like I had more in
me but when I pushed I couldn't get it out.  I was feeling so
much better decided to pull up my pants and start heading home. 
The pile of poop I let out was huge I couldn't believe it all
came out of me. But I honestly felt 10 pounds lighter and my
tummy was noticeably trimmer and wasn't firm to the touch like it
had been before.

That night while sleeping I woke up with another urge to poop. I
didn't want to bother my sister but I got up to go to the
bathroom. When I sat down I thought about doing the pinch but
after the relief I had felt earlier I just wanted to be empty so
I let it all out. And for the first time in over a year I was
completely empty. I have to admit it felt very strange after
needing to poop at some level constantly for so long. When I
looked in the toilet there was another log that was basically the
same as the earlier softer poop it was about 16 inches long and 2
inches wide. Luckily this was before low flow toilets and our mega
flush was able to handle it with out too much trouble. When my
sister woke up she said it stank like poo which it did, I was
totally embarrassed but I felt so much better.

After that my toilet habits for a long time were basically hold
it till I had a bad urge which after that stretching was about
every other week, I continued going to that same woods to poop
till I was done with high school and moved out of my parents
house.

At the time most of this seemed normal to me. Till high school
when I started to realize it wasn't normal but I still did it
anyways.
