Masturbation is the sexual stimulation of one's own genitals, usually to the point of orgasm. The stimulation can be performed using the hands, fingers, everyday objects, or dedicated sex toys.
For a girl, this would include rubbing her clitoris until she has an orgasm. Using some lube on the area, helps with the friction and enhances the stimulation. She also has a G spot which she may be able to reach herself and stroke it until she has an orgasm. It is best to watch videos that explain how the mechanics of orgasm work in a female, I will include that.
For a male, it involves the stroking of his penis with his hand in any way that produces these wonderful feelings. If the penis is erect at the time, stroking it can get it to become engorged with blood. The reason people masturbate is several.
First, its a good way for a young person going through puberty to begin to explore their sexuality. Its not a matter of losing virginity but a series of different experiences or steps they come across in their sexual debut or experience. Some people use it to relieve the high level of horniness they feels. Others use it also as a stress relief. Its one of the best stress relievers around for all kinds of stress, not just sexual stress. Some couples like to do mutual masturbation on each other so a person would use their hands on their male partners penis, and for the girl, her partner would use their fingers or hands on the girl.
As you can imagine, this is slightly more difficult than doing it yourself because you can't feel the stimulation through nerve endings as they are and therefore have no idea if what you are doing is working right. So requires a good level of constant communication between partners, saying when something does feel good and asking to change something to go faster/slower, harder/softer change location. It is a good idea to master getting yourself to orgasm first before trying to explain it to a partner. No there isn't just one way. Everyone is different, so with every sex partner, you have to learn from scratch, what works for them. If you do a search online, or even for videos on you tube, I am sure you can find lots of info. Here's the one video I promised.
