Brazilian wax worth it? How painful?

A.💕
So are Brazilian waxes worth it? How painful is it? How often do you have to go? Do they wax around your anal area too or is that extra? How long does your hair have to be to wax? I've seen about a centimeter but I need visuals not measurements lol... What about armpits? I hate shaving so please give me all the info you have!
