@LittlePanda1, are you female?
If you are, you are in the right age group, as you are of Child Bearing Age.- This will attract ugly 40+ weirdos who want children.
Do you have children? This will put off many manchildren but not all of them.
If you don't have children, watch out for the Disney Dad, who wants a EOWE nanny, he will probably not want children with you because he has Already Proved His Masculinity.
One child is more acceptable than more than one, if what male friends tell me, and a young child will be an asset as you have Proved That You Are Fertile, and will give a bit of the Madonna & Child touch. Also you'd be couple with a child not a family +mum's boyfriend.
Children might attract the married man looking for a bit of extra, as you will be busy with looking after your children, and, I hope, not in a hurry to introduce them to your new man.
I'm just being cynical of course, but I only posted a head shot and I got loads of messages. I am no oil painting and the years haven't been particularly kind. The photo was of me smiling and I have long hair. I think the smile and hair probably helped, but probably just being female was enough.
The men were 50ish, some not the best shape and looked old, some looked fine, most were divorced with children. I changed my postcode on my profile to a nicer neighbourhood. OK that's cheating but I don't want anyone following me home.
