Age Regression is a completely non-sexual coping mechanism. There are people that intentionally regress to deal with heavy stress and stuff, and there are people that involuntarily regress, too. If typing, some regressors may type more like this: "Hewwo! Is *name*, and I is *insert young age*! Is nice meets you!"
Person 1: Why is *insert person* acting so immature, like a child?
Person 2: Oh, that's because they use Age Regression, or agere, to cope with issues they are having!
They're sometimes adults that are dealing with trauma. And sometimes they're just pedophiles.
Person 1: What the fuck is this?
Person 2: It's called age regression.
Person 1: The fuck..? It sounds like something a pedo would use to excuse them trying to fuck a minor.
