chances are, you probably already know what masturbate means, and you're just looking it up to find out how to make yourself feel better. so, if you are a guy, wrap your fingers and thumb around your penis, and move it up and down. another way is to wrap your hand around your penis with one hand, while creating a "lip" shape with the other. usually this is done by putting your index and thumb finger together. now, the "lip" hand is on top of the penis, while the other hand is underneath. now, slide your hands up and down.
for girls, start by putting your finger (usually index or middle) half-way into your vagina. then move it around in circles. this will get your blood pumping. then, go further in, and start moving your finger in and out of your vagina. now, add a 2nd or 3rd finger, and thrust them into your vagina. when they are inside, jerk your fingers up and down, rather than in and out.
you can also fold a pillow in half, and hump away. it feels better if you put a can, or something hard in the pillow. you can also try this. put your heel under your ass, and into where you vagina is. rub away.
oh i love to masturbate when no one is home.
