I think the most logical explanation is the increased level of arrousal. It doesn't make sence medically that the volume would increase but you may have a good point about the diameter of the urethra. Physics tells us that if you push a given amount of fluid through a small tube you will get a higher pressure than if it is pushed through a large tube. Beachballs.
