Forgetting that you have pleasured yourself, and so you might do it again and again until the time you remember when it will be unusually powerful .
Amnesia theme mixed with masturbation trigger.
Might feel like you only edged even though in reality you have already orgasmed, so you take longer to reach a second plateau which is also more intense.
The act of forgetting orgasms becomes a game in its own right, and you win when the last orgasm of a session is particularly powerful.
For all listeners.
Lingering effects? Maybe longer more enjoyable masturbation..
