According to new guidelines issued by Planned Parenthood, a child's genitals don't determine their gender.

Planned Parenthood has devised a new set of talking points, tailored for preschoolers and for parents to address sexual issues and questions of gender with their children.

Under a subhead called "How do I talk to my preschooler about identity?" the organization recommends the following:

"When it comes to gender, ideas about what it means to be a girl or a boy are everywhere, and these ideas have a big influence on your preschooler. Learn how to teach your kid that their gender doesn’t limit them, how to talk about different kinds of families, how to know if your kid is transgender, and more."

According to the new "rules," Planned Parenthood said that parents should tell preschoolers that "everybody has nipples," regardless of gender. Additionally, they want parents to explain to their children that "boy, girl, man, and woman are words that describe gender identity, and some people with the gender identities 'boy' or 'man' have vulvas, and some with the gender identity 'girl' or 'woman' have penises/testicles."

"Your genitals don’t make you a boy or a girl," Planned Parenthood's website reads.

Planned Parenthood's previous guidelines claimed that "women have breasts. Men don’t." The elaborated further, and said, "boys have penises and girls have vulvas."

The organization also said that the old "birds and bees" adage should be phased out, and that children as young as preschoolers should be taught how women become pregnant — via penetration.

About sex and masturbation, Planned Parenthood recommends that a parent take a completely straightforward approach to the discussion.

"Conversations about sex and masturbation not only give you an opportunity to share accurate information with your kid, they’re also an opportunity to talk about your values. Your values influence how you talk about it, so think ahead of time about what messages you want to send."
