I think the correct answer must be John Barrowman (but I'd be thinking about David).

Oh, and what criteria do you use to judge the 'most erotic' answer?

A: John.

Because if you hollowed him out, you could use him to move rubble from the garden to the skip out front. David might just try to move in.

Very mean to make a girl choose!!!
But would have to be Barrowman as he makes me laugh and his singing in the shower would be awesome.

- Hello, I’m looking for a man.
- Well, you’ve come to the right place. That’s all we do here. You might say that men are our speciality.
- I know. That’s why this is my favourite shop.
- Thank you. So what kind of man are you looking for today?
- Um… I’m thinking Scottish?
- Scottish, very good. Very on-trend. Scottish men have been all over the catwalks this season.
- And I’m planing to wear heels, so he’d better be tall.
- We have some very nice men in the 5ft 10 range.
- Hmm. No, I think taller.
- 6ft plus? That will narrow things down a little.
- And I’d like him to be an actor. I’m going for a dramatic look.
- Special occasion?
- I’m thinking of marrying him.
- Oh, well in that case I can see you’d want someone to stand out from the crowd. Well, we have our basic Scottish actor range, and then our Premium range.
- What’s the difference?
- The Premium range are better looking and more famous. But they are priced accordingly.
- It’s a one-off purchase.
- Of course. So do you have any preference on what kind of actor?
- I like science fiction. Television science fiction, in particular. For a family audience?
- Gosh. I’m not sure how many of those we have in stock. Oh, yes, actually more than I thought. But I’m not sure if we can meet all your criteria. For example, here’s Douglas Henshell but he’s only available in 5ft 9 ½.
- 5ft 9 ½?
- His imdb page is very clear on that extra half inch.
- I’m afraid that’s a little short for me.
- I quite understand. I can offer Patrick Stewart, who is a little taller, and while he isn’t Scottish exactly, he has a good Celtic name, and he’s a timeless design classic.
- Tempting. I do like his voice, and he looks great in that Starfleet uniform. How timeless is he exactly?
- He’s currently 69 years old.
- Hmm. That’s a bit too timeless.
- I see. Well in that case, if your requirements are non-negotiable, it’s David Tennant or John Barrowman.
- David Tennant or John Barrowman?
- That’s all we have left.
- This is tricky. Will you be getting any more stock in?
- Not til Christmas, which is when we’re expecting our new Doctor, but he isn’t Scottish, and imdb doesn’t even list his height, so we’re anticipating that he might be quite short.
- I was hoping to be married by Christmas. Right. Well, in that case… God this is hard… and I hate making impulse purchases, but I’ve got to get to the bank and it’s closing in ten minutes… OK. Barrowman.
- Barrowman? Are you sure?
- Yes. No. No. Tennant.
- Tennant?
- Do you offer a refund or exchange if I change my mind?
- Unfortunately not.
- Tennant then.
- Definitely?
- Yes. Absolutely. He’ll go better with my handbag.
- Tennant it is. If you wait here, I’ll just go and get him wrapped.
- No, it’s OK, I’ll wear him home. Thanks very much.
- My pleasure.

Not sure I can compete with Marie's contribution which is of course in the classic mode of imaginary discourse that she has perfected over the years. Personally, only a Rosby scenario could top this writing.

I'll try to contribute something, but I feel I may disappoint ...

Posted - and here as well

* because he made my heart skip and my stomach turn when I saw him on a billboard poster
* because his physique is the kind that makes me smile inside
* because he has great hair
* because his native accent makes my mouth go dry and moves my womb
* because... I can't even say how other parts of my body react without getting obscene
* because when he smiles, honestly, perfectly, it is enough to dazzle my eyes
* because when he meets fans he is nothing less than kind and frequently generous
* because he seems to have a genuine affection and understanding of people's affection for him
* because he can turn emotions on the edge of a sixpence, from joy to despair
* because he knows just how to choke a line of dialogue to rip your heart out
* because when he laughs you never feel it is anything less than real
* because he believes in social justice and fairness
* because he loves what he does and can't get enough of it

So far, this could, reasonably be applied to either of these lovely males. But....

.... I don't need life to be a song and a dance, a show-stopping spectacle, a confessional, heroic demonstration - as much as that excites me.

My choice? He's the Doctor, MY Doctor, and much more besides. John Barrowman is a perfect companion, sexual tease, and flirt. But my choice would be: David Tennant.

PS of course David has to understand he's in a scrap to the end with Dougie Henshall...

David Tennant or John Barrowman?

I'm sorry, but that's not a choice at all. Tennant always and forever. He's a tall, skinny, geeky fanboy who has gorgeous eyes, amazing hair, and a fabulous smile. He's kind, patient, caring, considerate and funny. He doesn't believe he's sexy (which is more than half the appeal for me). He's quick-witted, intelligent and generous.

He's a brilliant actor and can turn his hand to anything, even playing two different versions of his character in one story (eg. John Smith and the Tenth Doctor in Human Nature/Family of Blood - Season 3 of Doctor Who). His villains are utterly chilling bastards who still manage to be attractive and sexy at the same time (which ought to be illegal!)

Despite being a legitimate star, thanks to Doctor Who, he doesn't behave like one; instead he remains down-to-Earth, feet-on-the-ground, ordinary, and it's very clear from set reports that he cares passionately about his co-stars having a good time.

And as Hamlet, last year, he was completely and utterly mesmerising.

I feel as if I could sit down and chat with him over a cup of tea about just about anything. (And I'd quite happily go further than tea and talk, if he was up for it!)
