This is such an interesting question!

First, I think the line between a shippy fic and a gen one can be very fuzzy. To me, if there is any attraction, it can be labeled shippy. And for the record, I don't think you need to worry at all about your femslash_minis fic being femslashy enough. Minis fics are supposed to be short so many of them turn out to be more of a character study with attraction or sex on the side than a long, plot-driven romance.

I also like your question about if not including graphic f/f sex suggests you are uncomfortable with f/f sex in general. Obviously, the fact that there are fewer femslash stories with or without sex than m/m slash stories is one thing that will never stop bugging me. I think a lot of people are uncomfortable with femslash and f/f sex. On the other hand, I would never suggest that one story without f/f sex would mean that an individual is uneasy with female sexuality. Plus, as much as I enjoy reading smutty femslash fics, that is not why I prefer femslash. I love reading about the connections between female characters and how they relate to one another.

So, yeah. Interesting question! Mind if I point other people this way to get their response?
