I think you would be able to find more responses on other sites. Sorry you are having difficulties. Part of it might be your choice of words. In some subcultures the q word is accepted. But for the large majority it does not seem to be as acceptable as the word gay. That just seems to be the way it is.
I have run into several who are gay on tour. Hetero males in general are unappreciative of aggressive advances by gay males (some very). Most are appreciative of advances by hetero females.
My suggestion would be to go by your sensitivity to specific cases and situations, and not to come across as aggressive.
Case by case awareness seems better than blueprints applied generally.
Hetero Latino culture has a strong or very strong element of machismo. I don't think most of them are terribly open to people who cross certain lines with them. Roberto Duran was flagship machismo, and the Latinos loved him for it. There are some great comments by Burt Sugar about his machismo and his place in their culture and hearts -- and another, more subtle side of machismo -- in a short documentary about Duran. You can find it on youtube.com.
Why do you have to make it an either-or--either pass/pretend (which feels dishonest or like you are hiding) or declare? It seems possible to find other ways.
