Thanks to the Iodine (clears your mind) I just remembered something. When I was in my early twenties and worked at an office at an University, I was used to guys looking at me, but in my twenties that changed.
Of course I was getting older and the new students indirectly were getting younger so probably to them I looked like an old lady.
So I was not even 45 and it happened to me, so don't put a label on yourself.
My grandfather got married,after my grandmother died, in his seventies and he acted the same as a young newly wed, that was a life lesson for me at 16, that people in love are all the same no matter what age.
