Dating/Romance Tours Legal In Philippines???? (Manila)

Hello. I run a small romance/dating tour company. In a couple of International cities I conduct small romance/dating tours. Introducing primarily American men looking for romance/marriage to local women. I am in the research phase of conducting a tour in Philippines. I arbitrarily ran across a blog post saying "romance tours" were illegal in Philippines.

If you could please advise as to where I could get some clarity/ruling on the subject.

Thank You
