If you are looking at Philippine women and you want children you are probably looking at a lady aged from 20 to 40. A 20 year old girl, looking for a man aged 40 to 60, may find herself attracted to a man who is 60 and looking for a lady aged 20 to 40. On the other hand a 40 year old Filipina, looking for a man aged 40 to 60, may find herself attracted to a man who is 40 and looking for a lady aged 20 to 40. With some exceptions, 18 is the age when a girl can legally date a foreign man.
There is some controversy about dating a 17 year old, with parental permission, in a non-physical, chaperoned environment but even that has been challenged under established Philippine law.
The things a Filipina look for in a man are stability, ability, personality and intelligence.
A typical Philippine woman wants a man who has financially established himself, to the point where he does not need to leave and go to work for days at a time.
She will probably want children, but men have the capacity to produce children well into their senior years.
Age is only important if it affects those characteristics.
