Re: Boxers and urine
Just a thought but have you ever thought about the fact that you are drinking too much water? If you have to drink that much you might want to talk to a doctor.
Back to the original question I think that as many people have said its a combination of nerves and just sweating it out. I am a tri-athlete and race sprint and Olympic distances and never had to use the restroom while racing and those last upwards of 3 hrs for an Olympic. I also think it has to do with the fact that you just aren't thinking about it. When someone is trying to beat the **** out you, you aren't really thinking about using the restroom.
