Two Sphincters

My intent here is not to be gross, just to encourage relaxation.
"When someone is a “tight ass” we already know that means they are rigid or resistant to spontaneity. This is more literal than many realize.
Sphincter muscles are like valves in a water system. They are designed to open when our body wants something to pass through, and close when our body doesn’t.
The only good times to clench our rear sphincter is 1) to hold in excrement, or 2) prevent something unwanted from entering. Any other times we clench we are reducing circulation and reducing the flow of sensation.
It’s a final attempt to resist our circumstances: if we can’t control them, we can stop ourselves from feeling them.
My clients who have had sexual problems almost always realize they have been unconsciously clenching their rear almost all day. Clenching is a way to literally reduce your feeling in your body.
Just as it’s near impossible to run slowly while pumping our arms quickly, it’s difficult to do anything gracefully with a clenched butt. An acting teacher told me: “The ability to relax the sphincter in performance leads to more freedom and availability in one’s work.”
Learning to keep that muscle group allows us to feel more and move and think with more flow. Here’s what we ought to know about the anatomy:
We have two sphincters back there
If you were a good student in 9th Grade Bio, you may remember that our anus is made of two sphincters that permit passage through the colon like the alternating locks of the Panama Canal. (Which you’d understand if you were a good student in 8th Grade History.)
The Outer Sphincter is well within our control. We contract it to hold in a fart. We relax it to take in a thermometer (hopefully.) Most don’t realize the Inner can continue clench even after the Outer has been relaxed.
