Let's call it the "drive to create," then, shall we? This makes it clear that non-creative writing such as software documentation isn't what's referred to.
The creative urge isn't usually specific to only one kind of creativity. If you have that drive, you have it; you can and do choose what form you employ to express it. Anyone who's only driven to write fanfic is usually motivated by a need not to create but to find a way to insert him- or herself into the universe of the fandom in question. It's more like an externalized fantasy than a true "drive to create."
Anyone who is driven to create can and usually does find multiple outlets for that drive. To suggest that fanfic writing can be as intrinsic to one's identity and existence as one's sexuality is, at best, naive.
