You would be better off joining a dating site and making contacts and friends online before you go there stating that you are just looking for dates not marriage so the marriage minded don't waste their precious time and money on you.
Do more research and dont believe every book you read. You will see the differences if you go to Colon in the day time and compare it to the bigger malls one is a tourist attraction because its different the other is like home superficially. Always being on your guard can get exhausting. Most Filipinas are looking for long term relationships. If you are a young man you have a better chance of finding like minded females who are ok with dating.
I think there's dozens if not hundreds of guys who have married prostitutes who they thought were like ordinary girls they met in the mall, but who they never realized, were prostitutes.
Its an easy mistake to make given the hard hearted attitude of western prostitutes.
