And how much can the anus and rectum stretch?
I've read on the sizes of anus and rectum: https://www.innerbody.com/image_digeov/ ... st%20point.
The rectum is a hollow muscular tube about 8 inches (20 cm) in length and 2.5 inches (6 cm) in diameter at its widest point.
https://www.britannica.com/science/anal ... 20connects.
The anal canal is 2.5 to 4 cm (1 to 1.5 inches) in length; its diameter is narrower than that of the rectum to which it connects.
How can the anus take anything that is more than 2.5-4 cm in length and 6 cm in diameter?
How can a rectum take anything that is more than 20 cm in length and 6 cm in diameter?
How much can the anus and rectum stretch and fit in themselves really?
If the penis is longer than 20 cm, or 8 inches, and thicker than 6 cm, or 2.5 inches, how can it pass through the anus and fit in the rectum? And if it does, it will hit the bend between rectum and sigmoid colon, the rest of the intestines.
Wouldn't the penis tear the anus and rectum, and wouldn't it hurt for both the rectum and penis to adjust and do a turn to move to sigmoid colon?
