I've had some thoughts today about the pic of you when you were young and my reaction to it. The psychological thought was that if I have really early attachment towards you, seeing you at a 'fatherly' age might have stirred those feelings in me and created the strong reaction (which my adult brain made sense of as attraction).
The simple thought is that here's a man I love, who cares for me and with whom I share everything, in a younger, bearded package. Why wouldn't I find that attractive?? Pretty normal reaction really and probably not worth analysing to death.
The truth is I think it's a mixture of those things and probably other layers too, but those were my thoughts.
