Should students shave at age of 14

My mom says i am too young to shave I think as a student it is better to remain clean shaved. This shows a bit of tidiness in the school environment. So, grab a straight razor and some gel or cream and always shave.Any razor should be fine and should not cut you if it's new. For girls i would say that you should not try to shave your legs if there are only few or little hairs on it.I know it is a bit embarrassing because your parents didn't think you are old enough to shave.Ask others and see how bad is your situation if yes then you can shave it...ask for help..
