Shaving down there😬

Ok I have problems and I don't want to ask my mom it is to awkward. I am 14 I can shave down there no problem but I get way to much red bumps and it's not comfortable. How do I get rid of these bumps and how do I shave so I don't get them?🤷🏽‍♀️ also is it normal to have a decent amount of hair down there even if it's cleaned up.
