Do a 12 year old get a hairy bum?

During puberty, which typically begins between ages 9 and 14, many adolescents experience various physical changes, including hair growth in different areas of the body. A 12-year-old may start to develop hair in the pubic region and potentially around the bum, but the extent and timing can vary widely from person to person. It's a normal part of growing up, and everyone develops at their own pace.
