Annette Bening
She was mostly naked in Grifters and STILL looks hot!
No doubt about it, Diane Lane.
She defines Hotness.
First I’d hop in ye olde time machine for Anthony Perkins, then it’d be back to the present for Ed Norton.
Then Seth Green on the way home.
(Rests her chin thoughtfully upon her hand, musing this ever so glorious question)… hmmmmmmmmmmmmmmmmmmmmm. What celebrity would I “boink”… hmmmmmm.
Firstly, I don’t “boink”, I seduce and plunder (ahem, I’m so vain!).
Secondly, does it make me a freak to love a dead guy? It does…? Shoot, okokokokokokokokokokokokokok…
(ponders some more)…
Well, if I could choose a dead man (not necrophilia, EWW! He’d be living, silly), I’d pick Jeff Buckley (Sexy modern bard. If you have to ask, I’ll slap you~~ We miss you, Jeff! 
). I would let him sooth my soul with his angelic voice and the god-given talent of his hands strumming a guitar before the lovemaking commenced (soft, wistful sigh). He is ROMANCE personified… pure yummy, this fellow!!
If I couldn’t pick dead (you picky people ), I’d pick Heath Ledger (handsome Aussie in bad movies~~ why can’t he pick a good script?). He is understated sexy, thoughtful sexy, quiet sexy…mmm mmm good.
Now, be off with you! I’ve got daydreams to give in to…
I’d love to know first hand what it sounds like when Holly Cole climaxes. I think I have a rough idea, but I’d sure like to be certain.
Four pages and no 1960s Barbara Feldon? Dopers, I’m ashamed of you… 
Rachael Leigh Cook, or if I had acess to a time machine, Diana Rigg in the 60’s
I have always loved Marisa Tomei.
and… dare I say it… Sean Connery. OK, I’m a straight guy, he’s 70, but DAMN!
Christopher Walken. ((from the Dead Zone. We can time travel for this fantasy, right?)
Josh Homme. (heaven smiles above me…)
Alan Arkin (from Catch 22 or Grosse Point Blank)
John Corbett (as Chris in the Morning)
Jimmy Fallon (as he is on SNL, not all spastic like when he appears on Leno or Letterman)
ooooh…David Letterman.
Chris Farley (what?!?..he would be funny as hell!)
Okay, Okay, Christopher Walken. I am certain.
Mainstream celeb: Susan Sarandon. Anytime from legal age until now (hey, she’s keeping Tim Robbins happy!), but especially anytime between Atlantic City and White Palace.
Non-mainstream: Whitney Prescott.
Gosh, so many choices…
[ul][li]Garrett Wang (Ensign Harry Kim, Star Trek: Voyager)[/li][li]Anthony Montgomery (Ensign Travis Mayweather, Enterprise)[/li][li]Von Flores (Agent Ronald Sandoval, Earth: Final Conflict)[/ul][/li]
Just off the top of my head. I can’t pick just one! (If I have them all at once, does that count? <hee hee!>) And that’s not even counting the girls! (My own loves Sophia Loren and Jeri Ryan, of course.)
Esprix
If we are allowed non-American celebrities.
Megan Mullally
In her prime:Virginia Bell
There’s just something about that grin. Oh, and other things.
Omigosh, I should have warned you–the above link is ** not safe for work**. There’s no actual nudity, but there’s a lot of skin showing. Sorry about that.
Mods, I hope I haven’t broken any rules, but if I have I apologize and won’t be offended if you want to kill the link.
Today: Beyonce Knowles, Salma Hayek, Miho Nakayama, Naoko Iijima
(both web pages are safe for work, but that second one may not be safe for standards of good taste and professional design)
If time travel is allowed: Laura Gemser, Sylvia Krystel, Catherine Deneuve
Alyssa Milano on my arm…
Teri Hatcher in the sack.
Tyra Banks or Marisa Tomei (why does she not get any work?).
I’d go gay for Keanu Reeves no problem.
Johnny Depp, now and always.
Wouldn’t kick Debra Messing or Catherine Zeta-Jones outta bed either.
