Like Johne says, "por la plata baila el mono". Be forewarned that gay "unions" are not contemplated in Dominican law. However, there are no sodomy laws on the books, and the age of consent is 18 years. Regarding possible consequences of your "gay public ceremony" you should keep in mind that public display of affection between two males is frowned upon in the DR, and may provoke a public disturbance, and maybe even arrest on moral charges, depending on the local authorities. I suggest holding the "gay ceremony" in another country, why not Jamaica?
