first things first, make sure she's okay with it, have you talked to het about it, is she happy eith it? it's probably best to talk about things before you do it rather than just asking a bit before you go ahead, as you never think straight whilst your in the heat of things?
i'm guessing your quite young, so just take care, and dont do anything you or your partner doesn't want.
if shes happy with it, if your comfortable with it and think she'll be comfortable answering, ask her if she fingers, and if she does, then shes probably the best one to tell you how to do things as everyone is different. if she hasn't, just take it slow and dont go too hard, its not a cock, be gentle. and also she will have no idea what to expect so it will be good whatever you do, the rest is about exploration and working out what's good for both of you.
hope that helps

can you tell me a good order in the manner of massaging the clit then go for the g spot or what order should i do those things assuming she says shes alright with it

First read the section on foreplay.

Definitely just try her clit first. The G-spot is more advanced. Stroking her clit is a much easier, more reliable way to give her pleasure. The main thing is to ask her what she likes. You can read all about different techniques on the clit pages.

Take your time and as already said above, don't force her into anything she doesn't want to do.
