your prostate is located about an inch or so inside the anus , its about the size of a walnut and to get to it, gently insert you finger (or cock, vibrator, dildo, or any other household item that'll fit lol) and go in to about your 2nd knuckle or futher....and gently feel around until you find it....you most likely (if you hit the right spot) will start to have the urge to piss (that means you have hit your g-spot) play around around and find what feels best to you and have at it....when you get ready to nutt, put some moderate pressure on your prostate......be prepared for cum to go flying everywhere, your whole body to shake, scream uncontrolably, and make sounds that you didn't know you could make.....just a note, before anything is inserted in your ass make sure its clean, especially your fingers, and make sure your nails are trimmed and smooth, and use pretty of lube.....hope you all enjoy (and you will....believe me)
