look at all pro boxers, they have noses that could land a boeing 747 on, they are as wide as they are long.
After a few tags on the nose and getting it busted a few times you'll not be worrying about your appearance lol.

it comes with the sport, like broken legs in football or tennis elbow in.....errrr.....tennis? :P

if your too afraid about getting tagged then your boxing training is going to suffer as you'll be too busy trying to clam up when the going gets tough.
