I’m pretty sure that I’ve already mentioned this, but for sometime now, I’ve been playing around with ideas for a humanized setting, focused on Spike in particular. To be precise, in this setting Spike is a half-human half-dragon hybrid, and because of his heritage, he suffers from… “unique” difficulties as part of his adolescence. There is his strength and his fire breathing, but probably the more significant challenge we faces is his… “urges.”
And yes, these “urges” are sexual in nature. Specifically, Spike is struck by an almost overwhelming desire to mate for a couple of days every month. It isn’t so strong that he’s incapable of controlling himself, but it is extremely uncomfortable and will resort to self harm in order to try to get it under control. Part of the story focuses on his efforts to find a spell or potion which can suppress these urges, if only temporarily.
I will admit, the story started out primarily as a clop fic. But as I thought about the story, I’m starting to debate whether or not it should be a clopfic. The story would be changed fairly significantly if the clop elements would be removed, but in all honesty the clop is secondary to Spike’s struggles to reconcile his human and dragon halves. And where they are present, they’re more focused on the sensuality and intimate aspects, since Spike actually really doesn’t like sex all that much (he fears that he might lose control and not stop if his partner tells him to).
The main thing that would change if it were changed if the story was switched from a clopfic to a more standard story would be the Mane 6’s awareness of Spike’s condition- in the clopfic version, Twilight is aware of it, and has been taking steps to “assist him” with it, and informs the rest of the Mane 6 as well. In the safe version, only Spike is aware of his condition, at least at first, and so struggles with it in silence, being too ashamed to ask for help.
