Medical science regards anal sex as “high-risk behaviour”. Physiologically, the anus is not designed for penetration by any hard object. The anal sphincter tightens ordinarily if stimulated, as a protective reflex action, and any attempt at penile insertion may be distressing even if done slowly and gradually. If the penis is forced into the anus, injury is possible. The lining (mucus membrane) of the rectum is very thin, tears easily, does not heal fast and therefore is vulnerable to infections. Also, the tears can enlarge to a fissure or a crack leading to the outside of your body. There is also a possibility that a fistula could open up, allowing faeces to re-route into the abdominal cavity or into the vagina. This can cause serious surgical complications. One may lose control over the anal sphincter causing continuous involuntary leakage of faecal matter.
“As a society, we need to learn to accept all “persons” with equal human rights irrespective of their choices, but we do reserve the right to reject certain “behaviours” that are injurious to the health of those persons or others connected to them”.
