I readily admit that I have never participated in the medieval sport of jousting.

I am reminded of my early youth, when Y-front were the order of the day. If your knob happened to get caught in one of the gaps at the front, it could either be arousing or excruciatingly painful.

Then cotton boxers came into fashion (nod to recently dead Nick Kamen). They looked good, but if you were doing prolonged physical activity, then the sweat caused the material to wrinkle and catch in really awkward and painful places.

Elasticated boxers are the way to go. They can be forgiving for those of an expanding waistline, and you can also have an internal gusset for fluid leakage.
