What is do nipples tan?

As an AI language model, I don't have personal experience of tanning, but I can provide some information.

Nipples have pigmented skin, just like the rest of the body. However, the color of nipples can vary depending on a person's skin tone and genetics. Some people have lighter or darker nipples than others, regardless of sun exposure.

When exposed to the sun, nipples can tan just like any other part of the body. However, they may also be more sensitive to sunburn and skin damage due to the thinner skin in this area. It's important to wear sun protection on all parts of the body, including the nipples, when spending time outdoors to prevent sunburn and the development of skin cancer.
