Jerkoff instruction is verbal and sometimes visual prompts about how a man should masturbate and when to orgasm, if at all.

During Jerkoff instruction, an instructor tells and sometimes shows a man how to masturbate. The instruction will usually tell men how hard or soft to jerk off, how rapid his strokes should be, and where he should touch. The instructor might say, for example, how quickly the other person should masturbate, or when he should pause.The instructor may also use a visual aid, like a dildo or vibrator, to demonstrate the right technique.

It is also known as Jerkoff encouragement, which is positive reinforcement helping a male to orgasm.
During jerkoff instruction, the instructor may aim to help a man orgasm as soon as possible or tease him a little. The instructor may want to prolong arousal and make the man wait a long time for an orgasm. A practice called edging may bring the man close to orgasm many times, but never let him quite get there.
