How to masturbate without any toys and with no lub and anyother thing ?

Your mind: masturbation is a normal sexual outlet and I suggest you let your body tell you what feels erotic or sensual. No toys or lubricant needed.

Genital stimulation : You may touch or play with your genitals using your hand in whatever way you find pleasurable

The old fashion: Most young women your age don't have access to toys. You can use your fingers and if you feel like you need lube, your own saliva is actually a very good lube. In addition putting fingers in the vagina and gettting them wet that way also acts as a good lube. As you age you'll probably find lots of items that you can use in place of toys.
