Many westerners just come for a vacation and sex tour (but more go to Thailand for that since Philippines is a Catholic country), but the infrastructure is sub-par and the disease welcoming you doesn't discriminate against white people.
Don't forget that the Philippines is one of the top destination for foreign pedophiles, especially those from the Western nations. And one advantage over Thailand is that in Philippines you will get real women. In Thailand you don't know whether the lady is a biological female, or a shemale.
