Thanks for the reminder. I'm the gay youngest son with one older brother, there's only five years between us, both same parents and both brought up basically the same environmentally etc, and I certainly was never abused. I've never felt the need to overthink it really though do remember hearing about that theory/study in the past and finding it intriguing. Women should be encouraged to try for more sons then, for the greater good (in an actual good sense, not the commie one!)
