A speculum opens a cavity so someone can see or so something can pass. Medical Graves and Pederson specs are metal or disposable plastic with a hinge and a bill. Fetish versions may add a lock that holds the bills open. The mechanics are the same: insert closed, open slowly, lock, do not forget you locked it.

Warm metal in water. Cold bills make every muscle clamp. Lube the outside. The cervix is not a target for sightseeing unless a trained person is looking for a clinical reason. For play, the view is often the point and should still be gentle.

Pinch points at the hinge can catch labia. Hair wraps. Have a plan to unlock with slippery fingers. Autoclave or boil only hardware that is rated for it. Cheap plated specs flake and then scratch.

Procedure energy

• Talk through each click of the lock.
• Do not leave a speculum open and walk away.
• Clean the screw thread; that is where grime hides.
• Pain is a close, not a push.
