I am a little confused. The thread title seems to reference attractiveness, but the poll seems to be about children.
Since the OP appears to have regrets about not having children, I suppose that is the subject that should be addressed as well. Here are a few thoughts.
Attractiveness (I am assuming physical or superficial) is like wealth, it can bring people into your life that you would be better not knowing.
Some women marry the high school football hero and ten years later wish they had married someone with a sense of humor instead.
I have observed that living by oneself is preferable to living with a mistake.
The maternal (or paternal) drive often envisions affectionate children. Asperger children often do not demonstrate affection. Some can even be heart breaking.
Divorce might seem to be an easy remedy for a mistake, but those who have been through it tell of a price that is paid that was never even imagined.
If you divide humanity into two groups, givers and takers, you might find way more takers than givers. If you have love in your heart that would sustain you through the difficulties of parenting children (Asperger children can even be more selfish (takers) than NT children), you might be a giver and that might limit your relationship choices to the more narrow field of other givers.
Age has a tendency to reveal the superficial and fleeting nature of physical attractiveness. What becomes more apparent are qualities like kindness, patience, and humor.
