Ask the Doc :: Talk to the Fist
Dear Dr. Jason,
How risky is fisting?
Doctor Jason’s Response:
Fisting can be quite risky if not done cautiously. First off, a significant amount of lubrication is required; you can never have too much. Secondly, protection--such as a latex-free glove--should be used; it provides protection from infection and injury for both parties. Thirdly, remember the story of the tortoise and the hare; slow and steady win the race.
Advancing immediately to an entire fist without proper preparation can cause physical damage, such as tears in the skin on the outside as well as tears of the rectum, which can cause a significant internal infection. Fisting can increase the pressure within the rectum, which can also cause a tear in the colon, as well as hemorrhoids. Insufficient lubrication can cause small tears in the rectum, thereby increasing the risk of acquiring sexually-transmitted infections, including HIV and Hepatitis. If no protective glove is used, then the fingernails can cause tears too.
Repeated fisting can stretch the natural muscular sphincters of the rectum and anus; these sphincters are necessary to prevent you from having an "accident" with your bowel movements. That’s not pretty for anyone. If you develop any pain or bleeding during the act, you should stop immediately. If you develop pain, bleeding, or discharge afterwards, then you should seek medical attention.
