AGP is innate. I think it's perfectly reasonable to say of a pre-pubescent male that they are AGP. Or a fetishist. Or a paedophile. There's no undoing it. AGP is the same as homosexuality in this regard.

There is zero evidence of this and the notion is ridiculous. People have immutable orientations, and they appear to possibly also have immutable femininity/masculinity, which is where paraphilias stem from.
