I’m a woman to start.

There’s two modes I’ve found myself in when not masturbating - I’m either purposefully staying aroused and denying an orgasm to heighten sexual tension and pleasure OR I’m not masturbating because life is busy for whatever reason and my libido diminishes over time.

So it depends. And I think everyone is a little different as well, so you might want to play with not masturbating to reduce sexual frustration to see if it works for you.
