The Enema Primer
Chapter 2, Enema fun and health equipment
About equipment, all that I have right now is garden variety stuff like the drug store sells. I do prefer the douche nozzle to the regular little 3 inch job. The only accommodations to my kink in my current equipment are two simple modifications for ease of play.
First, I ditch the toy S hook of flimsy plastic. I substitute a sturdy coat hanger. Preferably one of the expensive variety that have plastic bodies for suit coats and a heavy metal hook, capable of swiveling right the way around, at the top. The swivel hook will slip easily through the hanger hole at the top of the bag. Being able to swivel, it can be turned to latch onto different kinds of ledges and protrusions where you may, from time to time, wish to hand the syringe.
Second, I take the standard bag, put the enema tip on the end of the hose supplied therewith, then purchase another hose and set of tips. (You can get hose sets in most large drug stores.) I slip the second hose right onto the business end of the enema tip connected to the syringe. It fits perfectly and forms a nice, water-tight seal. I put the shut-off clamp and douche nozzle on the end of the second length of hose. This gives me a lot more freedom of movement (with 10 feet of hose instead of 5) and allows hanging the bag really high for a strong rush of water. I don't recommend the hang-ten enema on the first sitting, but it works great for me after I'm relatively clean inside.
In the past, I had a 7 inch plastic nozzle with a bulbous head. It was terrific. I had a colon tube, but didn't like it all that much. I like the feeling of the water rushing in. There are too few nerve endings way up inside where the colon tube goes. Thus, you can't get the sensation of the rushing water or the stimulation directly to the prostate.
I had an inflatable double balloon retention catheter too. I did like to use it occasionally for a retention enema, or a session involving a partner and extended bed rest. :-)
In a fit of self-loathing and internal weakness, I threw all those goodies away years ago. :-(
As to what you would like or dislike, I can't say. You are uniquely you. However, you do give a clue when you say you enjoy dildo play. If that's the case, you'd probably enjoy the larger nozzles too.
Re the colon tube, lots of folks swear by them. For some, they are the tip of choice. They do look _real_ sexy as you bury them deeper and deeper in your lover's rear. And they do make it easier to take a large volume enema without cramping. I like the pressure and cramping. I like the feeling of the water spraying on my prostate. It's an individual thing.
Re: "Inflatable double balloon retention catheter" To get one or not. Tough call. I'm thinking of getting one with a double balloon now because I've become interested in herbal enemas for health and pleasure. Herbals are most effective when retained for an extended time, and the balloon definitely helps. On the other hand, they are somewhat clumsy to insert and definitely on the messy side to remove unless you were already squeaky clean inside. If you don't have at least a moderate tolerance of scatological scenes, you might be better off to save the considerable investment.
Then there is the 4 quart bag. I'd love to have the pure latex one in natural amber color. They look so threatening, inviting, sexy. But $125.00 for an enema bag. I think not. I have a combination syringe for the 4 quart scenes. It is a standard hot-water bottle/syringe that the drug stores sell. The kind with a choice of screw in caps for the fill hole. One cap is just a plug and the other has a fitting to attach the hose. I've equipped it with the double-length hose I mentioned above. To fill it, I unscrew the cap/hose assembly, hold it under the tap, and fill to 2 quart capacity. Then I attach the cap/hose. Hold the bag up to expel the air from the hose. Now clamp off the hose. Dunk the nozzle in a gallon container full of water. Open the clamp, then put the bag on the floor and hold the water jug up. So long as the nozzle opening stays below the water surface in the jug, it will siphon water into the bag till it stretches it to its limit. To get more water, you have only to lift the gallon jug higher. I let it run till the jug is half emptied and another 2 quarts have bulged the syringe to a wicked looking bloated thing. The added advantage here is the swelling of the bag makes me tremble with anticipation. I know that what is happening to that lifeless piece of rubber will soon be reversed. It will empty its overloaded contents into me, and I will be getting engorged as it deflates itself. Also, the pressure developed by the stretching of the rubber membrane forces the water back out with a real rush at first, and you can feel it up inside you, spurting against your sensitive areas. By the time you get too full to take this rapid flow, the bag has gone back to its normal shape and the flow moderates. Works great.
