Riders don't normally feel an urge to go to the bathroom simply because of the sweat, body fluids would come out in perspiration instead of the usual route down there. But during rest periods in leisure tours, I find the male cyclists relieving themselves in the grassy area or anywhere where there is a cover like a tree or a wall. With female cyclists, it is not appropriate so the female in the group would look at each other with a pout.
A disadvantage of women riders.. in that department.
