I think the behavior defines the attitude in these things, so I would guess the behavior has ALREADY occurred.
I think a pastor, teacher, or parent, for instance, would have have grounds to wonder whether a kid who "come out" as gay (SSA) at 12 were molested somewhere along the line... But I don't think it's necessarily the case.
I am no expert, but from what I read, a not-insignificant number of young people experience SSA in early adolescence, don't "do" anything that crosses a line, and their feelings eventually mature into natural man-woman desires by their 20's.
