The nude swim has become such a popular way for young adults to learn about sex and sexuality.
But some experts say it’s not appropriate for kids to learn anything about nudity.
The rules about nudity are the same for adults and children, said Mary Jo Miller, director of the Sexually Transmitted Diseases and STD Prevention Clinic at Children’s Hospital Los Angeles.
Miller also said it’s too early to say whether the new rules will lead to fewer people becoming sexually active.
The Centers for Disease Control and Prevention says in general that most people are at least 18.
Miller said the guidelines should be relaxed for kids, but they shouldn’t be changed.
