protip: after you pee, squeeze your perineum up to your balls and the base of your dick. do it exactly like you would squeeze the last bit of toothpaste out of a tube. final drops will come out. it's been 10 years since I discovered that trick and I've literally never had smelly boxers since then, it works perfectly and only takes 5 seconds.
