Breasts and ass.
12 years ago, I would have said, emphatically, “leg man.” Asked to describe my ideal woman, I would have said that she would be tall, with long legs, a small butt, smallish to average breasts, and long dark hair.
How to describe my wife? Average-to-short (for a woman) with somewhat unremarkable legs, wide hips, short brown hair, and large breasts. And I think she’s the sexiest thing around, so I guess I’d have to say that I am now a breast man.
Why’d you limit it to two choices? You’re forcing the Ass Men into the Leg Camp by default. Not fair.
Because, to tell the truth, I’ve never understood the attraction to Legs.
Tossup for me between Breasts and Bottoms. Legs a long way third.
(And, of course, none of these is the most important. Having someone who’s warped the same way you are is.)
Intellect.
Breasts if I had to choose between the two.
But if I had to choose something other than face, hips. Perfect hand rest.
I’m generally a breast man, of the larger variety. However, the other evening I was at a gentleman’s club and had several dances from a dancer who was nearly completely flat-chested, except for some very interesting nippleage, which was quite pronounced… First time that had been something I’d been attracted to.
I’ve certainly seen some nice bums in my day too.
So I can enjoy both…depends on the situation.
Are you me? 
Legs. I like 'em long and lean. Usually that leads to a nice small butt. But that’s hardly the only criteria.
Yeah? Funny, I would have thought just the opposite.
Ha!
face, especially pearly white teeth.
[Two Construction Guys Talking]
Guy1: Wow, did you see the intellect on that one. Hoo, baby.
Guy2: Yeah, but she looks like the Harvard type. I’m more about MIT women myself. And don’t let me get started on doctoral disserations. I could go on ALL NIGHT.
Guy1: Preach it, brother! Oh, look, that one has glasses AND she’s carrying a laptop.
Guy2: Man, I love this site!

Guido: So, Mr. Kizarvexius, if that is your real name, my boss wants to know. You into ta-tas or gams? C’mon, you can tell me.
Kiz: “Ta-tas” or “gams”? Is that the subject of this interrogation or the lunch menu?
Dino: (Looms menacingly) Hey you little sh*tbag, show some respect. Or we’ll have to teach ya some manners.
Guido: Now, now Dino. It’s a fair question. We’re talking about women, Mr. Kiz. Chicks. Dames. Broads. So are you a leg man or a breast man? That’s all we wanna know. Then you can go free.
Kiz: Well, truth be told, I’m more of a personality man myself.
Dino: (Leans in close) Hey! That wasn’t one of the options!
Kiz: I don’t care. If you want to know what I find most attractive in women, it’s their personality.
Guido: What the hell are you talking about?
Kiz: In the long run, physical traits just aren’t that important to me. Given the choice between being with a shallow, brainless supermodel and a witty, intellectual frump, I’ll take the frump every time.
Dino: What are you? Some kind of f*cking communist?
Kiz: ….Um, no. But I like women with brains. What’s wrong with that?
Guido: Ya know, Mr. Kiz. I’m trying to be patient here. Really I am. But you’re not answering the question. I don’t give a rat’s ass one way or the other about brains. I don’t wanna hear about brains or personality. Fuhgettaboutit. So’s we don’t misunderstand one another, we’re gonna talk only about bodies. Get it?
Kiz: Okay! Okay! Put the car battery away! I’ll talk!
Guido: Easy, Dino. Boss won’t like it if you leave burn marks.
Dino: Aw, man. You spoil all my fun. (To Kiz) Now listen you little pissant. Answer the question. What does you find most attractive about chicks?
Kiz: A pretty face. Nice eyes. I like long hair, especially red.
Guido: You know, Dino. I think Mr. Kiz here is trying to have some fun at our expense. Why don’t you show him just how serious we are.
Dino: With pleasure. (Cracks his knuckles) Mr. Kiz. My partner here takes no pleasure in being harsh or cruel. But I do. The next words that come outta your smart little mouth had better make Guido happy. Udderwise, you will find that you are no longer capable of enjoying any part of any woman. So which is it? Ta-tas or gams? (flicks open switchblade)
Kiz: All right! All right! I’ll talk! Breasts. I’m a breast man all the way. I admit it! Just don’t hurt me!
Guido: Dino, report back to the boss. We got what we wanted.
Yeah, but you’re a heterosexual female, so I’m thinking that you and I have different standards. Believe me, I’ve looked at a lot of women–I’m not drawing conclusions based on a small sample.
Ding, ding, ding!! Any day.
Unless I could trade the ass for CZJ’s face, and then re-arrange the body accordingly.
As far as physical appearance goes, I’m another face man. Especially a good smile. But if it’s between legs and breasts, well, it depends on the particular legs or breasts in question. A fine specimen of either will certainly get my attention. Likewise for buttocks, hips, or midriff.
I’ll give you the “different standards” thing (hence my original “funny” statement), but me being a straight chick has nothing to do with it. I’m just as capable of noticing whether another woman has a pretty face or a nice body as the next guy – in fact, straight women tend to notice such things about other women. 
Besides, I’ve been alive longer than you, so I’ll wager that I’ve looked at just as many women (if not more). 
Everybody knows that. We don’t even have lexicographic preferences for the air we breath, so it’s safe to assume we don’t for everything else.
Breasts.
But not for me. For our children. The Shrutes produce very thirsty babies.
Shapely legs that can squeeze the juice right out of…
Thighs that can block out any outside sound…
Before I get more distracted, I’m a leg man.
