When you have a seat on the thrown and fire a log out no probs tthan you just sit there squeezing and grunting and no matter how much effort you put in there somethin still in there and its not coming out. You have to make the decision to wait it out 20 min. or just pick up your trousers and feel uncomfortable until later in the day when you can finish it off.
Sitting down ready to empty yourself and having to get up only half empty just shakes a man to his core.
