Pretty self-explanatory title, but just to be clear- what fictional characters have you encountered who, if they were real and you met them in the Waking, would you most want to have as your lover/husband/wife/significant other/prison bitch/concubine, etc.? It can be from any genre (literature, movie, television, graphic novel, comics, cartoons, etc.- except for Dot Warner, who is mine.)
This may be more relevant for IMHO, but since it involves film, TV, etc., I’ll put it here.
I’m gonna go with:
Friday, from the Heinlein novel of the same name
Willow, from BtVS
Deety Burroughs Carter, also from Heinlein, in Number of the Beast
Rogue (the movie version played by Anna Paquin), from X-Men
and as my concubine, Britney Spears. She’s fictional right?
and from my childhood fantasies, Dyna-Girl, of Electra Woman and Dyna Girl 
Ezri Dax from Deep Space Nine. Not only is she almost too cute (and I mean cute specifically), she’s also got just the right mixture of vulnerability, quirkiness, and placidity that I find irresistable.
Michael Tolliver from Armistead Maupin’s Tales of the City series of books
Wesley from The Princess Bride in the book and the movie
Dallas(played by Caspar Van Dien) in Modern Vampires(I don’t care about his politics, religion, or even having a deep meaningful discussion with him. WILD HOT MONKEY LOVE is what that man makes me want.)
Hard Harry(played by Christian Slater) in Pump Up The Volume. Purrrrrrrrr…
The college guy who gets Elizabeth Shue at the end of Adventures in Babysitting. Oh… that man still makes me melt. He’s amazingly stunning.
Mark Darcy from Bridget Jones’ Diary in the book or in the movie. Spank me Daddy and make me do bad things.
One last choice that is purely on animal attraction and nothing but… Bullseye(played by Colin Farrell) in Daredevil. I’d bitchslap Mother Theresa’s corpse on live television to get some of that.*
*To be clear: I’d think about trying to get around having to do that, but I would do it and risk mass international hatred and very, very demented people thinking I was cool to get Colin Farrell to nail me like a jackhammer.
Oy…
From the Dark Tower series
Charlotte, from Lost In Translation - but then maybe I’ve just fallen in love with Scarlett.
Hmm. Must meditate on this.
oops…totally forgot my absolute favorite of all -
Kaylee from Firefly.
:: drool ::
Kwerki from Ghastly’s Ghastly Comic, which there is no way in hell I’m going to link to here. Google, mang.
Ellen Cherry from Skinny Legs and All by Tom Robbins.
Excel. Or Hyatt. Hell, both of 'em.
The Monkey from Portnoy’s Complaint.
St. Germaine, from the Chelsea Quinn Yarboro books. I’ve often wondered who could pull off that character if they ever made a movie.
Q, from Star Trek.
Definitely Willow from Buffy, with Giles a very very very close second. Actually, let’s all just set up house together. 
Lucifer from the first Prophecy movie. And whoever Eric Roberts played in the second one (Michael?).
Christian Troy, from Nip/Tuck. I could tame that bad boy. 
I wouldn’t kick the Branaugh version of Henry V out of my bed (that movie was on last night, as a matter of fact).
And were I 16, I’d be all over Adam from Joan of Arcadia.
I reserve the right to add to this list as inspiration comes to me.
Masterharper Robinton from the Pern series as husband
Purely on sexual attraction:
Frost and Doyle from the Merry Gentry series by Laurell K Hamilton
Acheron from Sherrilyn Kenyon’s Dark Hunter’s
Madmartigan (from Willow) would be fun to dally with I think…
bobkitty - Thank you.
As for me, (I’m female, not male as the literary St. Germain is) I’d go with the above-mentioned vampire St. Germain or **Jamie Fraser ** or possibly Roger MacKenzie from the Outlander series of books. And either Mark Darcy or Mr. Darcy, as long as Colin Firth comes along for the ride. TV-wise, I’d probably go with Rupert Giles from Buffy. Hum. in. a.
StG
Can it be movies?
Captain Jack Sparrow
Han Solo
Indiana Jones
Robin Hood. ( Errol Flynn version)
Inigo Montoya
D-Day from Animal House
And last, and certainly not least, Ranger from Janet Evanovich’s Stephanie Plum series…humina humina humina…
When I was a teenager I was completely in love with Lloyd Dobler from Say Anything. In fact most of the girls I knew were.
My one and only True Fictional Love will always be Vina Aspara, from Salman Rushdie’s The Ground Beneath Her Feet.
For pure f*ck buddy Melrose Plant from Martha Grimes mysteries.
Now for husband the robot in Tanith Lee’s Silver Metal Lover
Wife? nah, I’ll pass unless she cleans
prison bitch ummmmmmm most of Roger Zelazny’s villians
Oh and I dont want to forget Number Ten Ox- big, strong, reasonably smart, mmmm
Almost all of Heinlein’s females, though I would prefer they kept their sense of self and personalities around me and not wilt and melt as they do when the Heinleinian SECOND STAGE MALE shows up.
Scarlett (played by the late Charlotte Coleman) in Four Weddings and A Funeral. She was so great, and I wanted to love and comfort her after she talks of the guys who bonk her and leave her. She very nicely offset the mostly obnoxious characters that populated this film. “Oh fuck…”
Sir Rhosis
Spike, Angel, and Wes from AtS (in that order).
Rhett Butler.
Indiana Jones
Captian Jack Sparrow.
Jack Bauer, from 24,
John Murdoch, from Dark City,
Benton Fraser, from Due South,
and Wolverine, Cyclops, Bobby, and Nightcrawler (shaddup) from X-Men 2.
The fourth Doctor, or, Brigadier Lethbridge-Stewart
