Fisting: health risks and safety rules
Definition : Fisting mainly exposes you to hepatitis C (via blood and shared lube), anal and rectal injuries and some STIs; individual gloves, your own lube, short nails, going slowly and staying sober greatly reduce these risks.

What is fisting?
Fisting means gradually inserting the hand, sometimes the forearm, into a partner’s anus. Sexosafe describes it as a practice of patience and gentleness, focused on pleasure rather than pain, requiring trust and communication.
What are the risks?
Hepatitis C
This is the main infection risk. According to Hépatites Info Service, any practice that can cause bleeding exposes you to hepatitis B and C, and that’s what is seen with fisting done without single-use gloves or with lube shared between several people. HIV rarely passes through fisting itself (CATIE), but other STIs do: gonorrhoea, chlamydia/LGV, shigella.
Injuries
Fissures, tears of the lining, and, rarely but seriously, rectal perforation. A damaged lining also becomes an entry point for infections during later penetration.
Chems
Sexosafe passes on doctors’ warnings: combining fisting with drugs (stimulants, GHB, ketamine) increases the risks: speeding up without noticing, loss of pain sensation, unfelt injuries, sometimes drugs taken anally.
Safety rules
According to Sexosafe and Hépatites Info Service:
- Nails cut short and filed so you don’t tear the glove or the lining.
- Gloves: a new glove per partner, and everyone wears their own gloves in group play. Nitrile is tougher and less allergenic than latex.
- Individual lube: everyone has their own tub, or single doses; in groups, only one person dips into a given tub. No oil-based lube with latex gloves (lube guide).
- Go slowly: listen to the body; pain is a signal to respect.
- A proper douche, two hours before, without overdoing it (douching).
- Sobriety or, failing that, very limited use and experienced partners.
- Stop at the first sign of bleeding.
When to go to A&E?
After a session, go to A&E straight away if you have:
- intense abdominal pain that persists or gets worse;
- heavy bleeding or bleeding that won’t stop;
- fever, a hard belly, feeling faint.
These may be signs of perforation: every hour counts. Say clearly what happened; staff have seen it before.
For milder injuries (fissure, painful bowel movements), a proctologist can help.
Sexual health
- Vaccines against hepatitis A and B.
- Regular testing, including hepatitis C every 3 months if you fist often.
- PrEP or condoms for penetration that follows fisting.
