The sigmoid flexure is an "S"-shaped curvature to the penis that is present in animals with fibrous penises (bovines, goat, sheep, etc.). Animals that do not have a sigmoid flexure of the penis include horses and dogs.
The function of the retractor muscle in bulls is to form a sigmoid flexure (s-shaped curve) in the penis in order to hold it inside the sheath when not erect.
Bulls have what is called the Sigmoid Flexure which is a muscle that expands to allow erection for copulation, and then contracts, pulling the penis back into the bull's body during the time when the penis is not needed.
The base of a bull's penis (inside the bull) is a sigmoid flexture, which is curved in an S shape when retrated inside the bull, held by muscles that keep it that way. When the bull is sexually aroused and extends his penis to copulate a cow, the muscles relax and the sigmoid flexture straightens out allowing the penis to protude to copulate the cow he his mating with.

Sigmoid colonThe sigmoid colon is the part of the large intestine after the descending colon and before the rectum. The name sigmoid means S-shaped (see sigmoid). The walls of the sigmoid colon are muscular, and contract to increase the pressure inside the colon, causing the stool to move into the rectum.The sigmoid colon is supplied with blood from several branches (usually between 2 and 6) of the sigmoid arteries, a branch of the IMA. The IMA terminates as the superior rectal artery.

There are actually more than 6. I believe they would be the cecum, ascending colon, hepatic flexure, transverse colon, colic (or splenic) flexure, descending colon, and sigmoid colon.
The sigmoid colon (pelvic colon) is the part of the large intestine that is closest to the rectum and anus. It forms a loop that averages about 40 cm in length, and normally lies within the pelvis, but on account of its freedom of movement it is liable to be displaced into the abdominal cavity.
The rectum is the terminal section of the alimentary canal; from the sigmoid flexure to the anus. The rectum itself is an opening, and a specific mass would be hard to calculate and rather small.
