Your problem will only get worse as you age. You'll need to plan your potty time ahead and take Imodium as an insurance policy. I spend lots of time fishing offshore in boats without heads and have seen my share of humiliated guys doing the squat of shame off the side of boats. Did you know that catfish are called "turdburglars". Girls, somehow, have much better control over their bowels and rarely get themselves into these predicaments. Also, the urgency can be proportional to last night's beer and Taco Bell intake. Good luck.
