Claims or Assumptions
Fisters have trained their holes so well that they can take a fist just as easily as a dick.
Reality
Fisting porn cuts out the warm-up sequence because it can often take fifteen minutes stretch the hole wide enough to take a fist, even with advanced fisters.
Mitigation
Always ask your bottom how long their warm-up typically takes.

Fisting leads to old age incontinence.
Fisters never experience incontinence.
Reality
Men in their sixties and seventies who have fisted weekly for twenty years or more do not report any higher level of incontinence than their non-fisting counterparts.
Most fisters have occasionally experienced a specific type of incontinence: Lube Farts.
When excessive lube is coupled with punch or depth fisting, the air that is pushed deep into the colon will eventually work itself down to the rectum as gas. If residual lube has pooled in the rectum, a lube fart may occur resulting in messy briefs.

Fisting Inevitably Results in Prolapse
Due to the stress and trauma on the hole, eventually anyone who fists will prolapse.
By following specific routines, any fister can develop a prolapse.
Reality
Several prolapsing fisters indicate there is a genetic component to prolapsing. Some men work diligently to weaken the muscles and ligaments to no avail. Others prolapse without any type of body modification training.

Claims or Assumptions
At mid-forearm, I'm past the second hole.
Any skilled top can work open the second hole during a session if given enough time.
The second hole works just like the first and can be opened with ease.
Reality
The first hole is composed of muscle that stretches with ease to complete its biological function.
The second hole is composed of ligaments that are attached to muscles. These ligaments and muscles straighten the hole but do not expand and contract nor open and close with stimulation.
It takes dozens, if not hundreds, of sessions to loosen the ligaments. Many mid-forearm sessions are often stretched rectums where the second hole has not been fully breeched by the meaty part of the hand.

Claims or Assumptions
All punching carries the same risk.
The second hole responds to punching the same way the first hole does.
The colon has the same resiliency and strength as the rectum and anus.
Reality
The second hole is mostly ligament with attached muscle while the first hole is all muscle. Muscle tissue can relax to prevent trauma and allow punching. Ligaments do not relax and contract. They open only through regular stretching. When a finger catches the side of the first hole, the hole gives and the hand passes through. When a finger catches the second hole, it can pull and tear the colon on either side of the hole.
The tissue strength and thickness of the colon decreases significantly with depth. The walls of the sigmoid are easier to rip than the walls of the rectum. For additional information, see:
Claims or Assumptions
I've reached the 3rd ring!
When a top is elbow deep, he's passed the third ring and is in the transverse colon.
Reality
Both the rectum and sigmoid have a high stretch capacity and can accept over 45 centimeters (18 inches) with ease. These sections of the colon float and can be moved from side to side across the abdomen.
The descending and transverse colons are fixed to the body and do not have any leeway in movement. Furthermore, at the third hole, the bend in the colon is greater that 270˚. It is almost impossible to pass through this bend with the limitations of the hand. Fingers may cross, but the hand will not.
In most cases, if a top feels a ring, it is a rarely accessed haustra segment with extremely tight bands.
