Scientifically speaking, what is the reason I enjoy holding in my shit for extended periods of time? I derive pleasure from exerting my anal muscles and prairie dogging my giant logs. I would constantly get turds break off from the main log and trickle into my underwear, especially at school. I would usually shit myself in this manner during math class. but I would never go to the bathroom. I'm enjoying a rather large log as we speak, in fact.
