This is such an interesting premise, and really well executed. The characterisations ring true, and Cas's asexuality is something I'm very eager to see explored, as well as Dean's reactions to it. In an excitable fashion I went and had a read of the comments about asexuality in your poll and very much hope you will take the route of compromise. Of course, it's your story and I look forward to seeing where you take this. I shall be waiting impatiently for the next part!
