You can google search it on the web but most of what you will get directed to are porn sites rather than helpful information. Best thing is to go to a public library and pick up books on it and skim them. Do a search in the library on the title of masturbation, there's an endless number of books on it, written by experts in the field of sexuality and usually they are filed in the same location in the library. There's no crime or shame in reading.
to poster. just rub your clitoris. it's the little deely bob between your vaginal lips. if that doesnt work, try fingering. Every girl is different, so find what feels right for you. why don't you give yourself a hand, or two! :)
Don't you think it wold be more fun to experiment with real sex with a male? Sex with a guy woul please you more than your fingers.
