How Does Shaving Work?

Can anyone tell me how shaving works and if it's painful or not? What's the difference between and electric razor and a normal one? What items do I need? Can I also shave other than my mustache and chin such as my cheeks? My cheeks and sides of my face have a little hair. Thanks! I just turned 16 and I'm learning how to live life.

basically shaving is painless if you are careful not to get cut 

reddit's 'wicked edge' thread is a good place to learn about this stuff

edit: though its probably not so beginner friendly...

if you dont have thick facial hair, just use an electric razor. quick and easy.

if youre cursed with facial hair of a 30yo, then go buy a razor and some shaving cream. gilette still sells 2 bladed razors i believe. practice with that and then move onto straight razors.

How much do electric razors cost and can I just buy any?

id say theyd be 20-30 bucks at the cheapest. you can even use a hair trimmer. it thats too much money, then goto your local supermarket and buy a razor and some shaving cream. 10 bucks should cover it.
