Edging is the process of repeatedly bringing you or your partner close to orgasm, then dialing things back by stopping or reducing sensation/touch. This is repeated as many times as wanted, until finally you OK the orgasm to proceed. This means that orgasms are delayed, and can be delayed considerably. Five minutes. Thirty minutes. Two hours. More. As long as all parties are enthusiastically consenting adults, it can be enjoyed as long as possible.
