I don't know where my g-spot is and I've never orgasms intensely.

That is because you are still very young and as you are getting older you will have a chance to know your body better and then you will be able to know what is OK for you, how to masturbate and how to have an intense orgasm.

In this case, g-spot stimulation is really necessary. You can try to do that with your fingers or some pleasuring toys (but you should wait with using pleasuring toys since you are still very young).

Try to relax as much as you can and be gentle. Don't use those brush handles or pencils, they can harm your private parts.

Fingers are just fine. 

Ok all you have to do is get two fingers and rub your clit clockwise then when you start to get hot you switch to counterclockwise

Better stock to one or two methods otherwise your valuable "private part" may get damaged.

WOW honey @13 you are doing a little more than you should be. think anyway, Ok I get touch yourself, but inserting objects into your "valuables" is probably not a great idea at your age. I'm not trying to be mean I PROMISE! Women have urges and the mind starts to wonder, but that I would say comes with life experiences and I cpouldn't imagine you having very many to make this a thought process. Now what is concerning to me is How are you doing this? Do you just sit in the bathroom and grab that brush & anything you can think of and insert it in yourself? Do you wash it off first ? are you using sterile things... please try what one of the guest posted... rub it and up, down, counter & clockwise IF this isn't doing it for ya, THEN apply a bit more speed to it and press harder on your clitoris...while going faster get to what feels good and stay at that speed and pressure until your satisfied . I am no pro! Just try other options before using unsanitary objects or strange things that can damage you. Women are special Vaginas cant just have anything put in it...well atleast not dusty, dirty, and germy YUCK! ATLEAST wash everything FIRST.
GOOD LUCK PlayfulKitten_14

I wash EVERYTHING before putting it into my vagina. I wash it twice actually. Then afterwards. I hate using the brush, did it once DO NOT want to go back! Sharpies are boring, toilet paper thing is gross and not that pleasureable. I don't have a religion against doing anything with my vag or whatever I just want some ways to explore.

Pretty much. Put your fingers in and straight up.but your g spot is about the size of a pea.so it might be hard to find. But you can get a cream at i think all sex shops that is great that will make it bigger for a little while. About the size of a walnut.
