im a girl and realy want to masterbate how do i do it 2 get the max of an orgasam

Every girl is different. Some prefer clitoral stimulation, penetration, or anal.
For clitoral, most girls like anything that vibrates on their clit.
For penetration, girls prefer objects of different shapes and sizes. Some have a trick to rubbing a certain spot inside your vagina.
For anal, it's just the penetration.

Just experiment with your body. Exploring is the only way to know what you'll enjoy most! :-)
