To me one of the #1 traits that makes a man attractive to me, is to feel that I am attractive to him. Otherwise, he could be Antonio Banderas, and he will be, to me, practically genderless. I am not attracted to men that are not attracted to me, and that has made my life quite easy and pleasant. And at present, I am not attracted to men other than my husband. I may find a man (like Antonio Banderas o Denzel Washington) handsome, as I can find a woman pretty, or a painting beautiful, but no sexual attraction.
So I really would not implement any strategy to find out if a man of any age likes me.
At present I implement strategies to make sure people know I am not available.
You know it's love when the pain of being apart is greater than the pain of being together.
