Masterbation for Beginners?

So I'm quite inexperienced in the whole sex department due to my incredible independence and very low tolorance for dumb guys, but I've been real stressed lately and got a couple sex toys online and really want to try them out but I'm not sure how? I've tried masterbating before and get bored because it doesn't do much for me. I'm not sure what's supposed to feel good or how to stimulate any areas... Anyone have any tips?
