Why do some people have big breasts and some people have small breasts?

This question is actually very easy to answer and can be explained from several aspects.

1, genetic. Many women's breasts are somewhat similar to their mothers. Although it doesn't matter much, there are also some genetic factors in it.

2. development. This is the main reason, because everyone's body is different and their development status is different. Some people have better congenital development, so their breasts will be full, fashionable and curvy. And some women don't develop well for some reasons, so their breasts are flat, a little small and unattractive. These congenital diseases are difficult to develop again unless abnormal means are used. Of course, there is no chance at all, but the chance is very small.

3. Man-made. This kind of artificial is divided into many situations. In general, young women's breasts are fuller than girls'. Because young women have been nourished by men after marriage, their breasts will develop again under certain circumstances. And after giving birth to a child, her chest will secrete milk, and her chest will also rise plump and round. Girls are just born and have not developed yet. The chest will be tall and straight, tender, but not full. Therefore, the breasts of young women are generally larger, while those of girls are smaller. Of course, there is another situation, that is, breast enhancement surgery. Now many women will do it, using surgery to artificially enlarge their breasts. Originally, the chest is very small, and it will become full after the operation to attract men's attention.

All the above are summarized views, but whether the chest is big or small, it is enough to fit your body. You were petite, but you didn't want big breasts. Some of them are unrealistic, which will only happen in animation.
