Man, I suck at titles

At present, I have 3 novels in various states of completion. In short:

Novel #1 is a completed first draft, at about 87,350 words (287 double-spaced pages). It's literary fiction, leaning toward romance. It's written in third person, present tense, and the main character's a woman in her early thirties. I have extensive notes to incorporate into the editing, but I haven't started that yet.

Novel #2 is about 60-75% written (first draft). It's currently sitting at 87,337 words (wow, so close to the completed first novel), and is 144 single-spaced pages. Oddly, I write in single-spaced, and double-space when the draft is done. It comes from a paper-writing technique that worked for me in college. It's also literary fiction, though it could also be considered mainstream fiction, I suppose. It's less "literary" than the first novel is. It's written in first person, past tense. The narrator/MC is a male, aged 26.

Novel #3 is still in the planning stages. I'm actually quite close to beginning the actual writing. This one's fantasy, most likely Young Adult (I may drop the YA aspect, but I'm not 100% set on that yet). I need to plan a wee bit more to figure out if it's more high fantasy or sword-and-sorcery. It took me 4 full days of research and brainstorming to name my main species and the assorted races within (in addition to figuring what to call the non-magical humans and what the other magical creatures/people were and what they'd call themselves). It took an additional 3 days to give my main characters (all 7 of them, plus an 8th who is the catalyst for the action/plot) names. Pronounceable names, without apostrophes. I'm currently just nailing down some of the main plot points before I begin the actual writing. It will most likely be written in third person, past tense.

There is a novel #4 lurking in the back of my head, but it's only about 20% formed. Once I solidify it, I'll post more about it. I originally thought it would be a short story, but I'm now positive it'll be at least one novel, if not a small series of them (urban fantasy).

Now, you'll notice I refer to them all as "novel #1" and so on. That's because I haven't titled them. At all. They haven't even had working titles. This is a new problem for me. I've never had a problem titling my work before this. Then again, everything before this has been short stories, novellas, plays, poems, and essays/articles. But with the novels, I fail. I have no idea why. In the past, the title of what I'm writing comes to me quite early (in fact, sometimes it's the title that hits me first, before I even have a somewhat coherent story idea). Sometimes they change. Usually, they don't.

I'm not quite sure what's up with this. I have no idea what to do about it. I'm very curious what will happen when I write my next short story--will it start out, as most of the others have, with a title that just smacks me over the head? Or will this problem carry over? I certainly can't leave these stories unnamed. It'd be awfully hard to pitch a story to an agent or editor with it nameless. I suppose that having a beta reader or two might help, just so I have someone who can tell me their impressions and with whom I can bounce ideas around (someone with an understanding of all the characters and little plot elements and such). But finding a good beta isn't as easy as many might think. Not only do you have to find someone who's WILLING to read the story (which, depending on their speed and free time, can be quite a time investment), but you also have to find someone who will help on the level you're looking for. A simple "yeah, I liked it" doesn't help at all.

Now that I've rambled about my title issues, I'm off to do a bit more planning on that third novel, followed by some actual writing on the second--I haven't done any actual writing in a couple of weeks. How naughty.
