Oxytocin release is responsible for the nipple becoming erect with excitement and stimulation, caused by contraction of smooth muscle underneath the skin of the areola which pulls on the overlying skin creating a goosebump-like effect.
This is due to your breasts becoming engorged with a rich flow of blood. In some instances, the areola may swell so much that it may appear that the nipples are no longer erect.

While there are a lot of reasons why nipples get erect, sexual arousal might top the list. More often than not, the first sign of sexual arousal in women is the swelling up of the nipples up to 25 per cent.
Your nipples normally become erect when touched or exposed to the cold. The areolas may become more firm as well. During pregnancy, Montgomery glands enlarge in preparation for breastfeeding.
Stimulating, caressing or simply holding breasts sends nerve signals to the brain, which trigger the release of the 'cuddle hormone' called oxytocin, a neurochemical secreted by the posterior lobe of the pituitary gland in the brain.
The more the nipple is pressed or stimulated, the more fluid appears. Yellow, green, or brown discharge is not normal and may be a symptom of an infection or other problem. Spontaneous discharge appears without any pressing or stimulating of the nipple. This is not normal unless you are pregnant or breastfeeding.
In response to stimulation or temperature changes, they harden and stick out even more. When this happens, they often become visible under clothes, underwear, or a bathing suit. Despite the fact that this is totally normal, some people feel more comfortable when their protruding nipples aren't visible.
It has been previously suggested that female breast morphology arose as a result of sexual selection. This is supported by evidence showing that women with larger breasts tend to have higher estrogen levels; breast size may therefore serve as an indicator of potential fertility.
As females get older, their bodies start to produce less of the reproductive hormone estrogen than before. Estrogen stimulates the growth of breast tissue, while low levels of this hormone cause the mammary glands to shrink.
The short answer is no. Although your breasts will likely grow larger before and during your breastfeeding journey, breast size is irrelevant when it comes to how much milk you produce. A mom with small breasts might have just as much milk supply as a mom with large breasts.
And these genetic influences don't only come from the maternal side: "Your breast characteristics can come from both sides of your family, so genes from your dad's side can affect what your breasts end up looking like too," adds Dr. Minkin.
The maximum volume of milk in the breasts each day can vary greatly among mothers. Two studies found a breast storage capacity range among its mothers of 74 to 606 g (2.6 to 20.5 oz.) per breast (Daly, Owens, & Hartmann, 1993; Kent et al., 2006).
While women with small breasts produce the same amount of milk as women with large breasts, they also have less storage capacity, which means the baby might take in less food during each feeding. You may utilize different breastfeeding positions than women with large breasts.
In general, taller women have wider chests so they can manage a larger breast size, whereas a C or D cup may overwhelm the frame of a smaller woman. If your breasts are too large, this may lead to functional issues such as chronic lower back pain and bra indentations.
They Break Records - The world's largest natural breasts belong to Annie Hawkins-Turner. She wears a 52I bra and they weigh 56 pounds each.
Gigantomastia or breast hypertrophy is a rare condition that involves developing extremely large breasts due to excessive breast tissue growth. It affects people assigned female at birth. If you have gigantomastia, you'll experience rapid and disproportionate breast growth.
When the gravity pulls the breasts down, those ligaments and the skin can stretch, and so the breast then droops. This depends on the elasticity of your skin and of your ligaments, as determined by your genes and diet, and also on normal aging processes.
When does breast development begin and end? In general, breast development begins between the ages of 8 and 13. A girl's breasts are typically fully developed by age 17 or 18, however in some cases they can continue to grow into her early twenties.
The Health Site suggests that if you are regularly monitoring your bottles for wear but they happen to be in good condition, a general rule is to replace nipples every 2 months on average.
Sensitive or sore nipples may be a sign of an infection, such as periductal mastitis. An infected nipple can be sore, and if the issue persists, the person should visit a doctor. Yeast infections can also cause nipple sensitivity and pain. In people with these fungal infections, the nipples may also appear flaky.
The short answer is yes, getting your nipples pierced hurts. But the level of discomfort can vary from nip to nip. Some peeps say it's just a slight sting while others say it feels like a fire ant bit their breast.
