Ask Four Poles

Here's a little something I spend most Tuesday nights doing...

First, lay some plastic down over the floor. In the center, place a large construction cone. Lubricate the outside surface of the cone with KY Jelly (an excellent water-based lubricant). Fill the cone (which should be fit snuggly against the floor; rub vaseline on the bottom if you aren't getting a sealed fit) with baking soda. Get yourself a standard enema kit and fill the bottle with vinegar. It has to be pure vinegar, not watered down! Insert the nozzle into your anus and fill yourself with the vinegar. Do not let the vinegar escape; you must keep in inside! Position yourself over the construction cone and, when you're sure the positioning is correct, allow the cone to start sliding into your ass. As the vinegar pours into the cone, the chemical reaction will cause a foamy eruption that is sure to bring you to orgasm! Don't stop, though. Seeing how far down the cone you can slide is also a pleasurable weekly challenge!

I like to masturbate with blood. Also, cat feces provide a lubrication thats unique and difficult to replicate. Start there and experiment further.

I heard using a cheese grater causes quite a stimulation.

There are several books on sexual health that cover this topic in great depth. I'd recommend buying one of these and trying whatever seems to interest you.
