I tend to be wary of m/f romance because of the female characters like that. It's less of a problem with other orientations. Iv'e noticed a lot less some/uke culture on this site than any others. I never got that into that anyway.
I'd get annoyed if I never got to add input into the story, but I think I'd be better than the opposite. I don't like doing it all. Sometimes you just got to be forecful back. People with that kind of personality usually don't mean to be elitist, but are just excited about their own idea. Feel free to add your own ideas in whether they ask or not.
