Breast growth is a normal part of development for girls and women. It occurs initially during puberty and may recur throughout life due to pregnancy and weight gain. While changes in breast size are not usually harmful, they can cause physical or image-related issues for some women. Learning what causes breasts to get bigger can help women accept their breast size by gaining a clearer understanding of what is normal and healthy.
For many women, breast size plays an important role in body image. Breast implants and bras made to lift, shape and enhance the bust serve as evidence of the central role of breast size in Western fashion and culture. When it occurs rapidly or unexpectedly, breast growth can be unwanted and may even cause back pain or other physical problems. In rare instances, breast growth can signal an underlying condition like a hormonal imbalance or tumor.

Here are seven things that happen to your boobs during sex.

1. They Become More Sensitive
Once that arousal starts to kick in, because your breasts are an erogenous zone on the body, they immediately become more sensitive to the touch. I'm not just talking about the nipples, but the areola, too, and the breasts as a whole. It's like goosebump city up there.

2. They Get Bigger
The body goes through four distinct phases during sexual intercourse : excitement, plateau, orgasm, and resolution. It’s during the plateau phase that the body sort of expands and swells, in anticipation of an orgasm. While your vagina expands about two-thirds its usual size during this phase, your boobs also get bigger ― up to 20 to 25 percent bigger to be exact.

3. The Areola Swells
Not only do your boobs increase in size, but so do your areola during sex . This is a combination of the breasts becoming engorged with blood which results in the size change. Sometimes an areola can swell so much that it can look like the nipples are no longer erect ― which isn’t the case. As long as you’re aroused, those nipples are staying that way.
4. They Release ‘Scented Sweat’
Well, to be more specific, it’s the apocrine glands in the areola that are releasing pheromones (that "scented sweat". While you may not be able to actually smell it on a conscious level, both you and your partner will be able to detect it, not even realize it, and you’ll become even more sexually attracted to each other.

5. They Tell Your Brain To Release Oxytocin
When the breasts are fondled, by hand or mouth, the
stimulation of the nipples send a memo to the brain telling it that it's time to release oxytocin. Oxytocin is also known as the love hormone, because it makes people feel all lovey-dovey, and is a major component in creating an emotional bond during sex.

6. They Can Aid In Achieving An Orgasm
According to a Rutgers University study, there’s a neurological link between nipple and clit stimulation . What this means is if you’re struggling to orgasm, stimulating both areas can help in achieving climax. In fact, there are some women who can come from nipple stimulation alone. I know! It's not fair AT ALL, but good for them!

7. They Change In Color
The combination of estrogen rushing through the body and stimulation of the blood vessels leads to a pink rash that shows up both underneath the breasts , as well as on the sides of them. This pink color can also spread to the upper stomach and neck. Also, shortly before this, the breasts can appear ― ever so slightly ― tinted blue as veins in the breast become more visible thanks to vasocongestion.

Of course, after sex, they go back to being your awesome every day boobs, but just like the rest of your body, they definitely enjoyed the ride.
