IMHO, the size of a woman's boobs is of the utmost importance. Yes, personality obviously matters, but if her body isn't hot enough, she isn't worth it. With that said, the two things that determine a woman's physical attractiveness-for me, anyways-are her legs and her boobs. In this case, if her boobs aren't big enough, I won't date her.

 I have to admit I'm partial to a healthy sized chest. Depends really on the build of the person.

 Breasts are the frontal visual cue of a woman's backside. Meaning the more voluptuous her breasts the more probable that her lower end (birthing canal) will be able to birth a healthy child

 Big breasts are more attractive to men because it is in their genetics to think that way. It goes back to the days of the caveman. The cavemen would go after a women with larger beasts because she would be able to produce more milk to feed his children as appose to a woman with smaller breasts who would not produce the same amount. The idea of larger breasts (though now changed) of being better is still more or less embedded within the males' genetic.
Apart from that women with larger breasts do often appear more confident. I'm wear a size D bra and am more confident about my body and they way my clothes fit much more than my old friend who was barely a size B. In my opinion confidence is a turn on and if women have both confidence and a large bust then they are more attractive then those who don't.

 I am average in cup size & I feel larger (not massive) breasts are extremely sexy. I feel ones who decide on implants should take it easy & try & to keep them somewhat in proportion with your body so they don't scream FAKE.

 I agree with the first person on here. Breats are great, but not to be smothered in.

 How is this even a debate! I love big breasts. Especially if they are natural. I do not like implants! I am so much more attrcted to large breatsed women! But it is a subjective thing!

 I want it!!! It doesn't matter how goodlooking you are if you have big breast, You know your going to get a date...

 Yes, because it's eyelevel for most men in the world

 The only way that i see it serves a purpose is women who have had to have 1 or both breast removed. For a cancer patient. They are usually women who have surived this and of course thats the only way i would even think of having this done.

 This is an area where our brains take over and the old 'caveman' instinct comes through; we males can't help it. We are programmed to seek out the most fertile and physically attractive female to carry our genes forward into future generations. Flat chested women can be extremely attractive in other ways of course; an example of this was the late Audrey Hepburn. But it is a fact that in the area of raw sexual attraction to the male the Marilyn Monroe's will win every time.

 I adore big breasts!

 Big boobs are good, but they should be natural and not created by surgery.

 There's definitely a too-small: Mosquito-bites are out.

 I'll go with the guys that say it depends on her body proportionally.

Personally, on average, I think C is the best size, but if you're a B - fine. If you're an A - fine.
I don't really care. It's not that big of a deal.

I think women tend to over exaggerate men's liking of big boobs anyway. Most guys don't know what a D looks like. This one girl I knew that was a double D definitely didn't look like it.
It only looks weird if you're like a size 2 with D cups or something.

 It depends on your body type but i would say medium would do not to big or to small bcuz you don't want to look ridiculous

 Having big breast with the right bra 2 support it makes a lady sexy.i mean its good 4 a girl 2 have a breast well proportioned 2 her body.i dont agree 2 the notion dat girls with large breast are cheap.i mean i know it makes us look attractive which is an advantage to us cuz it makes us look confident,smart,in-control and sexy.i mean who likes d idea of having 2 small berries on d chest..larger breast are more gorgeous,sexy and ATTRACTIVE

 Big Breast are better .As a woman with big breast .I have found that men seem to like the big ones ..Why do you think alot of women have there inhansed.Because men like them better.

 No they don't. Good size in proportion with the rest of the body breasts look the best. Breasts aren't indicative of either fertility or ability to nurse the young. If anything, smaller breasts are indicators of youth, since younger females tend to have smaller breasts. Women who have gone through pregnancy or are nursing have larger breasts. Look at ancient Greek statues, this is where Western beauty ideals stem from - small breast, shapely buttocks, narrow (but not too much) waist. Surprisingly, women with large breasts are viewed as easy, which isn't in women's best interests if they are looking for long-term partner. Bottom line of all this is, breasts alone may be initially attractive (ie quick hook-up), but breasts alone in any size aren't what men are looking for in women long term.

 I believe they are to most men.

 Why in the world would I ever play with one of God's wonderful creations? I'm smaller-chested and very greatful because I don't have to worry about knocking things over with my boobs when I go shopping (pregnancy was a total nightmare!!) or my shirts popping open at the bust at the worse possible times. I can also walk between people and navigate crowds easily when I'm out. I'm actually the smallest one in my family. (Mom had to have bras custom-made. Not to mention the creases in her shoulders and the infections under her breasts -- OUCH!) Picture this: Sitting down to Sunday dinner with 8 aunts who have breasts that take up the space your dinner plate usually occupies. It's no wonder I didn't want to eat all those years!

 Go to any bar on a Saturday night and see what girl is getting all the action.

 Boobs get attention

 As I hate to say it I think more men prefer larger breast. Of course some women are to large.

 Just as you said, "in terms of attraction", I think you are right, larger breasts are more attractive than smaller ones! I feel that most of men love larger breasts, they always talk about the size of womens breasts even in public!

 It depends on the person however in todays society bigger is always better

 Full breasts make a woman so much more attractive. God Luv'em!

 Well it is actually a known fact that women with bigger assets are prefered i mean why would a woman with a falt chest or real small breasts be attractive??

I'm a Bi girl and i know a thing or 2! Lol

 Yes, because boys prefer it in a women ,like my friend who has bigger breasts than me has had more boyfriends.

 Yes, as for as human instinct goes. Women with larger breasts and smaller waists are subconsiously thought to be more fertile, therefore more sexually attractive
