"Edging" is a type of sexual activity where a person tries to delay or hold back their orgasm for as long as possible.
Imagine playing a game where the goal is to not start laughing when someone tickles you. You try to hold back the laughter for as long as possible.
People who "edge" during sex are trying to delay their orgasm by stopping or slowing down the sexual activity right before they reach the point of climax. For example, they might stop touching themselves or their partner for a few moments to build up the sensation before continuing.
This can make the orgasm stronger and more intense when it finally happens. It's like waiting for a really awesome roller coaster and feeling the thrill through your whole body when you finally go down the big drop.
Edging can be a fun and exciting way to explore your body and your sexual desires. However, it's important to communicate with your partner and make sure you both feel comfortable and safe during the activity.
