Does everyone have anal hair?

Anal hair length is a common physiological phenomenon, and not everyone will have anal hair length. Whether human hair is strong or not is closely related to genetic factors. Some people are born with strong hair and have long hair in many parts of the body, including the anus. However, some people are born with weak hair and have no hair in many parts of their bodies. So there are many people with hairless anus. Generally speaking, people who think that anal hair is long will have a strong sexual desire, but this is also lack of scientific basis.
