Most guys figure out pretty easily what to do to get themselves off, but the female body is more complicated and mysterious. There are a lot of different methods for women to use to stimulate themselves to orgasm, and what they choose to do depends on what feels best to them. Some women discover when they're young that it feels good to rub their genitals against sheets or blankets, or an object like a teddy bear, pillow, or furniture. They may continue using this method into adulthood. Others prefer to use manual stimulation, caressing the clitoris (the button-like nub protruding above the vagina) with the fingers to bring on a climax. Some people use objects, anything from hairbrushes to hot dogs, to stimulate the clitoris and insert into the vagina. Some women like to use a vibrator or a stream of water from a shower or faucet to hit their hot button. People can be very creative.
If you are confused about what a clitoris is, see the link below for a 3-D diagram of the vagina.
When you're exploring self-love, keep in mind that it can take a while for a woman to reach orgasm - depending on how turned on you are and how your body works, it can take anywhere from two minutes to twenty or more. Just relax, do what feels good, and when you find something that feels really good, do it more. If you want some ideas, there are web sites that offer masturbation tips and instructions on how to make your own sex toys.

Masturbation is defined as (I quote) "Exciting oneself by fingering your genitals". This is exactly what both sexes do to masturbate. Some women will actually stick a few fingers in, while others prefer a dildo or a vibrator. I've heard of a case where a cellphone was inserted and called. Anyway, try experimenting with what you like the most.
Generally it isn't anything like the way a man does it. Some women like penetration during masturbation, but most use a rhythmic rubbing of the clitoris. Usually with light pressure either in a circular or side to side motion.
Try Google and type in "Methods of masturbation for females."
Almost all female masturbation techniques will focus on stimulating the clitoris in a variety of ways until orgasm is reached. The best way to go about this task is to find a nice, quiet, private place, such as in a bedroom or where most men and women masturbate, the shower. If you're like me, you usually only resort to masturbation when you feel the need for some release of sexual tension, like when you're horny. Of course, masturbation just plain feels good, and doesn't depend on anyone else's ability to satisfy your needs, so often it is a great way to just let loose and relax. There are three main types of masturbation: manual stimulation involving the hands, water stimulation involving showers and jacuzzi jets, and auxiliary stimulation, involving dildos, vibrators, and other sexual toys. Part of the fun of masturbation is self-discovery.
There are many different techniques used to masturbate. You have to experiment for yourself to find out what works best for you. One way is to use your finger. Just explore. Another way is your bathtub! Position yourself under the tap so that your genitals are directly under the running water. Let the water continuously hit your clitoris. Some women swear by it!
Most often women masturbate by rubbing their clitoris similar to male masturbation but smaller. Often women enjoy the feeling of penetration at the same time. Some women enjoy only the penetration when masturbating but it's not as common as clitoral stimulation.
Masturbation is often done to satisfy a need, but it can also be refined to an erotic art in its own right. For many women, it is during masturbation that they experience their first Os (orgasms), have their first multiples, discover the G-spot and explore their innermost and possibly taboo fantasies. One good reason for experimenting with new things initially during masturbation is that you are in control and nobody else is involved or need know any details. There may be some kinds of sexual fantasies - especially the more audacious ones - that are best explored in the first instance in the privacy and comfort of masturbation. Take your time, start with your breasts (rather than the clitoris), fantasize and fantasize, and work your way down. Relax, wallow, enjoy, and O and O and O. Woman who masturbate can use all sorts of objects to masturbate with: hand, vibrator, cell phone* on vibrate mode, rubbing a stuffed animal between the legs, etc.).
*It is generally not recommended to use objects other than those designed especially for the purpose. Using household, or everyday, objects can be hazardous, especially because they are usually not sanitary, and they can also have sharp edges or points that can cause injury. Avoid these, or use with great caution.
As mentioned in the first paragraph, individuals, especially girls, are often discouraged from masturbation. Despite the lack of evidence, jargon-filled statements are often used to incite fear of negative physical effects. Don't be put off.
A female may masturbate in many different ways. For one she can use fingers or a dildo to penetrate her vagina and also g-spot if she can reach; alternately or at the same time she may stimulate her clitoris by rubbing or stroking it. Before masturbating in any way a woman should be sure that she is properly lubricated, either by her own natural "lube" or by a store bought brand or something. Masturbation is a healthy expression of one's sexuality and desires; an opportunity to safely explore one's fantasies and as such finds highly versatile expression from individual to individual.
