Another popular Philippines dating site, Pinalove (‘Pinay’ means Filipino woman) has at the time of writing ~600 girls online, ~150 in Manila. You can filter for men, women, and ladyboys, and choose which ones can see your profile or not.
At the time of writing there are ~2000 girls online.
I wrote a trip report of getting laid on Filipino Cupid here and Dante wrote one here.
Buy a one year membership at Pinalove and the price drops to $8/month.
This site has girls from all over Asia which is useful when travelling, a large portion of the members are Filipinas though.
Some Pinays will hear about this site but not Filipino Cupid or Pinalove.
