I recently wrote a gay-male story, and after research, I decided that I wanted to use the word "twink".
Having no idea whether it was on the green list, grey list, or red list of naughty words, I asked privately for clarification. The advice I got was to search the published stories for that word to see if any stories included it.
That worked for me as 4 pages of stories came back... so that word was included in my story. π
