If you are a girl: when u stick two or one fingers, a dildo, or a vibrator in your vagina

If you are a boy: you use one hand and put it in a shape as if you are holding a mug then you put it around your penis and rub your hand up and down continuously

Most of the time people do it for pleasure because it should feel good!!!
Guy one: did u masterbate last night?

Guy two: yes! It felt good!
Get the Masterbate mug.
