My mom has been cutting my hair for the last 14 years but I want to go to a barber shop now and I don't know how to tell the barber how I want my hair to be cut I'm a boy by the way?

Is there one other boy you can talk to? If there is not, it is time you tried to make a friend. Ask your friend how he describes he wants he hair cut. Is there someone who has his hair cut they way you want yours cut? Tell him, "I like the way your hair cut looks. How do you tell the barber you want your hair cut?" A compliment can get you a long way in life.
