You can have it on sneak peek which will mean the title and description shows in your profile, but unless you hit the publish button it's not listed anywhere, and it's only accessible to people who have the direct link.
Or you can have sneak peek off which does keep it completely private.
Not assuming this is your intent or anything, but keep in mind though that any explicit fetishy stuff will still be removed if it's stumbled across, particularly if there are images. There are other sites for that kind of thing.
