There is legal age for paid because prostitution is illegal in Philippines .
Legal age for sex with foreigner is 18+
For local to get a girl pregnant? No limit - even 13 is ok !
There is a silly law in Philippines enforced on foreigners (if you become target ... ) that says a girl can't be alone with a man more than 20 years older - again don't ask how it goes for 70 year old senator having 17 year old lover....
And if cops really want to set you up they can refuse the birth certificate of girl and send her for dental age check and claim she is minor.
Hence my preferring girls with baby than no baby - former high chance above 18, latter ? No clue.
And Filipinos are good at making fake ID for work and there being no official ID, I encountered few girls in LAC who turn out to be below 18, when I tested saying I can try to get them job in Singapore, they blurt they can't get passport because they are below age, I don't mess around with UA girls. Never took them out.
The youngest a friend encountered was 14 pretending to be 20. Lucky he found out before leaving the bar.
