13 year old girl. How can I masturbate to get an orgasm

I know you are older now, and hope you have found some answers, but...

No pun intended, but if you stick with it, these things come in time. The brain is really good at figuring out what feels good, and losing what doesn't work so well. Sex feels good for a reason; we are SUPPOSED to like it. So, like anything that we are driven to do again and again, we LEARN how to make it work better over time. You might consider shifting your focus away from your clitoris though, and onto somewhere else beyond the obvious -- nipples, belly, inner thighs. Have you slipped a finger or two inside yourself to massage your G-Spot? It is the rough-feeling place on the upper inside of your vagina, kind of just "behind" your clitoris. It sort of feels like the roof of your mouth. This rough spot is meant to excite both you and your lover (Nature is assuming it's a male here) by stimulating the coronal ridge of his penis to bring him to orgasm (to ejaculate his sperm) inside you. But you can massage it yourself to lovely, intense effect, and bring yourself to orgasm from this alone. In concert with your clit and nipples etc., you should be able to get there on a regular basis.

But remember, your orgasm is not just driven by your clit (or your nipples, your belly button, your anus, your mouth -- whatever). In short, the physical sensations you create with your fingers are only a PART of what goes into your orgasm. Most of it is actually in your head. Your BRAIN, your MIND really drives your body when it comes to orgasms. The brain takes the sensations you create and mixes them with memories, fantasies, images and other stuff in your mind to begin the process that culminates in orgasm. A lot has been written about that, here and elsewhere, but it bears repeating. Orgasm is a delicate dance you do with yourself. Lots of things go into making it happen, including strong feelings of love for a partner. Lots of things can also get in the way -- subconscious fear of punishment, thoughts of being "bad", etc., even desires for a particular, absent partner can distract you or detract from the pleasure you want and deserve. You may need to give yourself  PERMISSION -- the freedom -- to have and enjoy the orgasm(s) you deserve.

So, keep exploring the sensations your body can create, and Good Luck!

I really need help because i don't know if this is normal, so i've been masturbating since i was 11 and i'm now 13 almost 14 and no matter how much i maturate i just can't seem to cum, it feels really good and all but after almost 3 years of masturbating i've never came and i'm kind of worried due to that fact but i've never done anything about it besides just continuing on trying to make myself cum, there are times where it feels so good that i'm very loud but i've never came and i don't really know if that's normal or not

Well first, let's try to let go of the idea that anything can truly be said to be "normal" when it comes to human sexuality. Worrying about failing to be "normal" can sabotage your efforts better than anything else. Indeed, there are any number of women who rarely, if ever, achieve an orgasm. They've gotten pregnant, raised children, and never actually had a full-blown orgasm. So for them, a lack of orgasms is "normal". In fact, it is often through making love with someone who ISN'T their husband that many of these women finally experience orgasm. Not what they expected at all. But given that you can feel sensations strong enough to make you shout or moan or squeal or whatever you do, it is likely that you could achieve an orgasm if all the conditions are right. In other words, although it's POSSIBLE, it is highly UNLIKELY that you have a physical problem. Physically, your "equipment" seems to be functioning ok. Assuming you are not on any prescription drugs like anti-depressants (which suppress the nerve impulses that trigger your orgasms) then there is something of which you are not aware in your mind that is not allowing you the freedom to "let go". As I said previously, for some reason, you are not giving yourself permission to lose control -- to go all the way, over the top with complete abandon.
Forgive me, but it really sounds like you are stopping going "over the edge" into orgasm because something about the idea bothers you, somewhere deep down in your psyche. I know from my own experience, that when I cannot cum (either through masturbation or during sex) , it's because I don't WANT to ; I'm distracted, or I just don't feel like I'm doing the right thing somehow. For example, when I have engaged in anal sex, which I'm not really into, I just can't cum no matter what i do. Something about what I'm doing is bothering me and shutting down the sensations to the point where continued stimulation actually begins to hurt. No matter how hard i try, no matter how much I THINK I want to, I just can't lie to myself about being excited enough or focused enough, or whatever. So it just isn't going to happen.
Short of piling on G-spot stimulation and porn, etc etc etc, there is no magic bullet of which I am aware. I can only suggest that you look seriously at how you actually feel about giving yourself over to the abandon and loss of control that leads to orgasm. It may be hidden, it's probably not what you expect, but your mind is incredibly powerful in these things, and it sets the rules whether you like it or not. Please try to consider carefully how you really feel about cumming. Make sure everything is as you need it to be (no parents around, no neighbors or siblings to hear your sounds, whatever). Try to relax, especially if it's "not happening". Focus on the wonderful sensations you CAN achieve, and give yourself over to them. I believe you can do this, once you find the hidden key that will unlock your orgasms for you.
