Underwear
Everyone has their own preference on underwear. If you know what works for you GREAT! Keep doing it.
A lot of scouts that go hiking are plagued by chafing. Chafing is a rash typically in the groin caused from friction of moist skin rubbing against skin. It can be extremely painful if it happens. A lot of young men chose not to discuss it because it is an embarrassing topic. Well, if you have ever experienced chafing, here is the solution!
To prevent chafing find a pair of firm fitting athletic underwear, with long legs. Your goal is to secure your manhood so that there is no movement or skin touching skin. That is the best way to prevent it. Make sure as you are hiking the boxers stay in place and do not start sliding down.
If you anticipate any chafing issues on the trail, the best overnight cure is thick diaper rash paste. Something like Desitin.
