What you do when there is nothing to do.

Something done to one's body to relieve horniness. When a woman's pussy becomes wet, she will massage her clitoris and other surrounding pubic areas. Also, she may slide a finger/fingers/toy/small object into her pussy to imitate a penis. Men's dicks will become hard when they are horny, so they resort to rubbing their penis up and down causing stimulating friction. These physical interactions are also sometimes accompanied by audio or visual stimulation.

The best thing you can do when you're alone

Something Everybody does I mean EVERYBODY!!! (except people with cameras in every room, but the fund a way around it)

When a man or woman, uses a body part to allow themselves sexual pleasure.

Masturbation often results in a mess of genital fluids. These fluids can be used in many ways such as glue, fertilization, or even for a sweet taste.

To masturbate in a male would be to grap your penis and rub it up and down in a continuous motion.

To masturbate in a female would be to either rub you vagina up and down with a few fingers or to stick a long straight peice of plastic in the shape of a penis(a dildo) in the vagina and pull up and down.

To jack one's beanstalk.
Or, to choke one's chicken.

This is what I do when I see something that excites me and there are no males around. I go find a comfortable sitting and relax. I take my pants and undies off then spread my thighs. I start rubbing the inside of my thigh to get me warmed up. I am already a little wet by now. Then I lick my two fingers and slowly and softly run them across my clit. aahh this feels so good. I'm moaning in anticipation because I know what is about to come. I then lick my fingers again and start at my clit, slowing guiding them into my hole. I make a soft back and forth motion, then as hard as I can shove my fingers as far back as they can go. i moan. I continue doing this a few times and then pull them out. ahh. I am dripping wet at this time. I make a circular motion around my clit and glide acrossed it. I am just teasing myself at this time. I shove my fingers down in there again and quickly go back and forth and around and I do this over and over. I continue moaning louder and louder making weirder and more exciting noises only to turn me on more. I am at the best part now. I pull my fingers out suck them to get all the juices off and then put them in there for one last time. I am working at a fast rate now. Flicking my clit with one hand and jamming my fingers in with the other hand. ahhh. I want to cum so bad I continue my motions. I start breathing harder and moaning louder. I squeeze my titties. I finally cum. I moan as I cum. I rub the juices all over my body and lick those fingers enjoying every last drop. oh man that was amazing.
