If you've got an idea that you really love, please feel free to write and not bother reading through this. If not, though, hopefully something in here will be helpful.
Generally, I like: queer communities, hurt/comfort (especially emotional), slice of life/day in the life, friendships, AUs, magic, happy endings, friends with benefits, people behaving like adults and talking to each other (rather than hoping the other person will read their mind/their weird hints), created families, kid fic, cats, bisexual characters, established relationships.
I don't like/don't want to read: I'm only gay for you, we're the only gay couple we know/that seems to exist in this universe, coming out stories, women needing to be rescued by the men, UST, problems that could be solved by talking to each other, meddling friends (we know you love each other, you just don't see it, kind of stuff), horror.
