Anal Sex and the Irresistible Urge to Poo

Anal Sex and the Irresistible Urge to Poo

How to Stop or cope with the irresistible urge to poo is a common question raised by Newbies to anal sex. The irresistible urge to poo is seen as a problem for the inexperienced who are concerned about making a mess (literally a mess) of things. However, it is also essential for opening up the inner anal sphincter (IAS) and thereby avoid straining the sphincter which can be a source of great pain.

Enemas for Irresistible urge to Poo

This is the primary reason why so many who indulge in anal sex or anal play insist on cleaning their ass with an enema before they begin. Dirty or clean anal is all a question of degrees. At one end of the scale are those who say there is no way of eliminating every last bacterium from the anal canal so it is never clean. At the other end of the scale there are those who say “If you can’t see anything its clean enough and by the way I wear a blindfold.”

A good enema gives people the confidence that nothing is going to get shitty regardless of the sensations they experience. So cleaning your ass out guarantees the irresistible urge to poo is not caused by poo. There is a MaxPrivate article that specifically deals with Eating and Enemas for Clean Anal Sex to provide you with that confidence. But if it is not poo causing the irresistible urge to poo then what is it? Here I deal with why you get the urge, how you can use it to your advantage and how you can overcome it.

What causes the Irresistible urge to Poo?

So what causes the irresistible urge to poo? There are a particular bunch of nerves in your rectum that are part of the enteric nervous system (ENS).  These neural receptors in the wall of the rectum react to pressure and stretching. These receptors are connected back to the spinal cord but their signals are not passed up to the brain, so your brain is unaware (which is to say, you are not be aware) of any stretching or pressure these nerves detect in the rectal walls. Instead, these rectal receptors trigger motor neurons that relax your inner anal sphincter (IAS) directly. It is the relaxing of the IAS and pressure on the anus that your “Brain” feels. The “urge to poo” is your conscious becoming aware that something is opening the exit.

Because there is no connection from your brain to the motor neurons that hold your IAS shut you cannot consciously hold the IAS shut. While you cannot control the IAS and your brain never “feels” the nerves in your rectum being simulated (in the normal sense), you can feel the IAS relaxing and other sensations caused by movement in your bowels. That is what the conscious mind equates to the need to defecate.

Normally, when you feel the need to defecate  your conscious mind reacts immediately, tightening the Outer Anal Sphincter (OAS) to hold the back door shut until you get to the toilet. In a normal state, when you don’t need to defecate, the IAS provides up to 85% of the closing force on your anus. For most people, even when they consciously clench their ass (tighten the OAS) as best as they can, it is still no where near as good at keeping your anus shut as the IAS.

Using the Irresistible urge to Poo

To make anal sex/play easy you actually want the IAS to let go. This is why you need to be confident that there is nothing waiting to come out. You need to know it is only that which is being stuffed in that is causing the IAS to relax and your inexperienced brain equating that as an irresistible urge to poo.

To make the IAS relax you need to get something in your rectum to put pressure on the walls and stretch them. That is why it is so important for the inexperienced to have their ass played with before penetration. At the same time you don’t want your conscious mind to be tightening the OAS just as you are getting the IAS to relax. You will go from straining the IAS to straining the OAS. It all feels just like any pain you get from straining muscles.

So making sure you are clean before you start means you can go with the irresistible urge to poo knowing these is no poo there. Let your ass open. When you feel the irresistible urge to poo start consciously pushing out just like you are trying to poo. That opens the OAS and that cock or toy will slide right in. To take bigger things up your ass you actually don’t want to relax at all, you want to push like you are going to do a big shit. Most people will take 8 inches balls deep on the first push by doing that, but it takes metal practice.

When the Irresistible urge to Poo is too much

This is where plugs are particularly useful training tools as they train your consciousness to accept bulbous things in your rectum and let your OAS relax along with the IAS.

With anal experience everyone’s consciousness learns that the loosening of the IAS does not always equate to poo. It doesn’t take very long before you anus starts winking and relaxing in anticipation of penetration and the pleasures to come.
