Forensic Science: Getting assfucked by a horse is as bad as Anal Fisting

Neue Studie im Journal of Forensic and Legal Medicine: Similar mechanisms of traumatic rectal injuries in patients who had anal sex with animals to those who were butt-fisted by human sexual partner. (via Improbable Research)

Abstract: „Injuries to patients who receive anal sex from animals are mechanistically similar to fisting-induced rectal damage. Among zoophiles, the mode of harm occurs through blood-engorged, interlocked penis that causes tissue lacerations upon retraction from an anus. In people experimenting with fisting, repetitive stretching within anal canal and of external sphincter causes the internal injuries. The mode of physical stimulation explains the extent of injuries in fisters vs. zoophiles: in fisting, the pressure applied by hand is controllable proximally around and within anal sphincter, while penetration by the animal penis is unpredictable and occurs within the proximal anal canal.“

In any case, assfucked by a horse or fisted in the bum: Watch after your soft tissue. Now you know. (Also: What about anally fisted horses? So many questions.)
