The age difference is what bothers me. Not the nationality or the process. “Dirty old man” comes to mind.
As I understand it, women in the Philippines are, in general, more mature than their counterparts here and much more marriage-minded than people of their age in the West.
Just because foreign brides may appear exotically sexy and a man's wet dream doesn't mean they're sex slaves and cater to a man's purient interests.
Women that know what they want (a standard among Filipina's) are not cupie dolls catering to the furtherance of an old man's dirtiness, rather ... she is more likely to instill if it wasn't there in the beginning, or remind a man ... a woman is an honorable human being and you will treat her with respect.
