Gay Long Distance Relationship document?

Hi! I´m looking for a good scientific paper about Gay Long Distance Relationships that I could publish in my website ( Protected content ). I have one or two, but I would like to have some more theorical documents. Do you have an idea of where I could find something like that? Do you know books or any contacts at universities, like professors or researchers busy with that subject?
Please take a look the website: Protected content
and contact me if you need anything!
