Fisting is the slow insertion of a hand into the vagina or rectum. It is an advanced stretch, not a party trick. Nails, jewelry, and hurry are how people tear tissue. Trimmed nails, gloves, and more lube than seems reasonable are the baseline.

The receiving body leads. Fingers add over time. The widest point of the knuckles is the moment to wait, not the moment to prove a point. Pain that is sharp is a stop. A full, intense stretch that the person still wants is a different signal and they have to be the one to name it.

Gloves protect both people and make jewelry a nonissue. Afterward, watch for bleeding that does not settle, fever, or pain that worsens. Those are clinic signs.

This is the wrong act for a first night with a new partner and a bottle of wine.
