Also can try a way I used to masturbate anyhow.
You get on your knees (sitting upright), spread apart like you were straddling something.
Then you insert 2 fingers, palm up, w/ like the heel of your hand pressed against the clit.
Then you just put your body weight on yoru hand...and basically just hump your hand lol.... that might give you an idea of the rhythm and motion that you enjoy.

I am pretty sure a guy is going to enjoy any kind of motion. My b/f can last forever when I am on top... mostly b/c of course I am not pumping as hard and fast as he would if he was in control....
