Why are breasts sexual? How are they considered a sex organ? What is their function in sex?
Breasts have a lot of nerve endings just below the surface of their skin. Where nerve endings are found in dense concentrations, the sensitivity of the skin surface is greater then surrounding skin. Breasts are intended to feed a child, and in order to facilitate that function, the nipples are highly sensitive (stimulation of the nipple area causes the brain to release hormones that will produce milk). For the woman that is not lactating, stimulation results in a sexual sensation. Nipples are two of several areas on the body that are referred to as erogenous zones.

Why are men so attracted to breasts?
Most men in our society are not subjected to (allowed) the sight of breasts under the average situation. Anything that society keeps covered general causes a natural curiosity that is often expressed by sexual sensations in the male brain. In some societies of this world, where no male (except for the woman's husband) is allowed to see any part of a woman's body, just the sight of her bare ankle will generally cause a man to have the same sexual feelings that they would here if they saw bare breasts.

Why are men's breasts not considered a sexual organ, but women's are?
Society has done this to us, and it started many, many years ago. The ancestors of many of the European settlers in our country (and others) made "Royal Decrees" that determined whether the "ladies of the court" should allow their breasts to show in public or not. Men's breasts are commonly exposed, so we do not build a curiosity about them. Also, many of the world's religions set rules or laws that continue to govern many of our attitudes about the human body (or parts thereof).

Is it true that nipples get hard when girls get turned on? In cold water, why do the nipples get hard?
The nipple will become more prominent (stand out) when it is stimulated by sexual excitation. The same will happen to a male, and it will usually happen when the person is cold, or if they are frightened, or any of several similar situations.

Is nipple size related to sexual stimulation?
The nipple becomes more prominent, and the breast and nipple will actually increase in size slightly when the person is sexually stimulated, but a person who has larger nipples will not necessarily become more sexually stimulated (unless they have a larger number of nerve endings in the nipple).

What is an Areola?
The area that surrounds the nipple. The areola will often be a different color than the surrounding skin of the breast. It might be anywhere from a very light pink to a very dark brown-black, it will change color slightly at the time of puberty, and it will usually become darker and wider when the woman is pregnant (and breastfeeds). It may be an inch in diameter or four inches in diameter (increasing when pregnant (and lactating)). It will usually contain small bumps ("Montgomery's Glands') and may contain body hair.

Why do breasts jiggle?
Two thirds of the AVERAGE breast consists of the breast tissue that is involved with the milk production and delivery. The other third is nothing more than fatty tissue. That is not all bad… fat fills in between the other parts to make the smooth, characteristically breast shape. The outer skin and the suspensory (Cooper's) ligaments provide the support for the breast. They pull up while the fat and breast tissues push down. This constant battle is visible as a bounce, or a jiggling movement.

Why do girls have different size breasts?
Barring any influence from injuries or diseases, the size of a woman's breasts will be determined by the genes that came from her mother and father. Fatty deposits on the body, pregnancy and breastfeeding may modify her appearance. Surgery is also a possibility. The thing to remember is that no two women have identical breasts, and very few even have a matched pair, so just about anything goes as far as being normal. When young women are developing breasts, one breast may develop more quickly than the other, causing undue alarm. The breasts will usually balance out by the time their body reaches the adult stage of development.

How can a woman increase breast size?
Breasts will finish developing, and then no amount of creams, hormones, or hypnotism will change their size.

Breasts contain no muscles, so no amount or type of exercise will cause a change in the breast size.

Extensive development of the pectoral muscles (that are BEHIND the breasts) may cause the breasts to be pushed about a half an inch further from the chest wall. However, that much exercise may cause the woman to lose part of her body fat, and some women actually have a negative net effect (get smaller)… (but stronger… LOL). Breast size can be temporarily modified by losing or gaining weight, which will change the amount of body fat that a woman has stored in her breasts. Unfortunately, she cannot control where the fat will be deposited or from where it might be removed. Pregnancy and lactation will make a breast change in size, but that is only temporary. Then, there is always surgery.

Is it normal for your breasts to hurt when you bump into something with them or push on them?
Breasts are just like any other flesh on the body. Bumps and bruises will cause pain. If a pain is noticed in a breast that has no cause, such as a recent bruise or something, pay close attention to it. If you do not know the cause of it, or it does not get better in a few days, ask your personal health care provider to check it out. It is better to be too cautious then to ignore it. It may need attention now.

What is the average woman's breast size?
Until a few years ago, the average American breast size was 34 B. It has since changed to a 36 C, due to the large amount of women that have had breast augmentation surgery and the fact that the American public is getting heavier.

If a woman is generally small, will her breast size most likely be small also?
No. Breast size has nothing to do with a woman's height or body size, other than if she puts weight on or takes it off, the breasts MAY gain or lose fatty tissue.

Can eating fattening foods give you bigger breasts?
It is possible, but not predictable. The body may add inches to the hips instead. If she eats less, fat MIGHT come from the breasts, making them smaller than they were before.

What is Hypertrophy?
This is a term for excessively developed breasts.

Does a bra affect the growth of your breast?
Yes, but not the way you want it to. There is a lot of discussion about the possibility that the suspensory ligaments that support the breasts increase the same as any other ligaments in our body do: they become stronger as they are given more weight to bear. If the bra takes the load that they should be getting, they have no reason to get stronger, so they remain weak. When the bra is removed, the weak ligaments will not be able to support the breasts, and that will allow the breasts to sag. A ligament is just like a muscle, and just like a muscle, you must "use it or loose it".

Do bras shape the breasts?
Temporarily. In the twenties and the thirties, bras were used to flatten the curves since the "boyish" look was "in Vogue" then. When the bra was removed, the breasts returned to their own 'natural' shape. When the bra was removed, the breasts returned. In the fifties, bras were shaped like the bumper guards of a 1955 Cadillac ElDorado. Madonna brought them back (in brass, not chrome). They were so pointed that they looked like they could hurt you. Foam rubber "falsies" were popular for placing inside a bra to exaggerate the actual size of the woman's breasts. In the sixties, we saw the "braless movement", and the bra industry were running scared, so they came out with the "natural look" that made breasts actually look like natural breasts. One bra in particular was called the "NoBra Bra", with very natural shaping and transparent fabric. Today, we are able to buy just about anything that we want. When augmentation surgery (implants) fell from our graces, "WonderBra" types came back, to make breasts look fuller and larger than they really were. All of these bras shape the breasts… for the time that they are in place. When they are removed, the breasts still return to their natural shape.

Are bras good for you?
In the sense that they may provide comfort, security, and modesty, and that they move the breasts into the position on the body that the current fashions in the stores require, bras are good. If they are causing breasts to sag, as some people believe, and if they are causing a restriction to the lymphatic system of the body, then they are not good.

What happens if a girl wears a bra ALL the time (except for showering)?
Given what they have found so far, researchers recommend that we limit ourselves to no more than 12 or even 8 hours of bra usage during any day (24 hour block of time).
