how dose a girl pleasure herself?

First off, don't judge, please I'm embarrassed enough by asking already... Uhm, I was just wondering, how dose a girl pleasure herself? I mean, I've done it a few times but I want to do it properly now, I've heard using a vibrating toothbrush on your Clitoris can do it, but do you actually put the toothbrush inside yourself? or not... And when you finger yourself (This will sound really dumb) were do you put your finger's and how far do you go? What ways do you know of pleasuring yourself? Please help, Thanks
