its normal for most guys going through puberty to want to fight. Testosterone causes this. Ive been in lots of fights. but you need to know if you can fight first. Dont get overly cocky. I dont worry about getting in fights because i know i can win. Im a freshman and im 6 foot 1 and i weigh 230 and i can deadlift 600 lbs. bench 250. and reguraly box. When you can ripa hole in the side of your 40 lb everlast heavybag, you know your good to fight.
