Ladies, please, what's your preferred method when masturbating?

Through photography commissions, I have been fortunate to see many women masturbating. Over 40 including GFs and FBs and a few others. They all used a different technique or a variation from a more familiar method yet they all reached their orgasm. Some used toys whilst others used the fingers of one or both hands. They did it in a variety of positions too. Some working slowly others very quickly and others speeding up as they progressed. Some stopped and then after changing position, began again.

So ladies, please, what is your preferred method, your preferred position, rate of movement and why do you prefer those ways over others?
