I do approve of the no-clop. It's completely unnecessary for this story.
I'll happily admit that I've read a few fics that contain sexual content, and sadly the fics that doesn't have it as a "main" feature often get too caught up in that, and suddenly everything is about that, everything else is forgotten...
It seems that suddenly introducing it to a story that doesn't need it is like building a wall, and forgetting to put a door in it.
