What is reproductive and sexual anatomy?

Reproductive and sexual anatomy includes your genitals and your internal sex and reproductive organs. Everyone’s reproductive and sexual anatomy looks a little different.

What parts of our bodies are sexual?

Reproductive and sexual anatomy (also known as sex anatomy) includes the sex organs on the outside of your body and the sex and reproductive organs on the inside of your body. Some examples of sex organs are the vulva (which includes your vagina) and penis. Reproductive organs include things like the uterus and testicles.

That being said, any part of your body can be sexual. You might have heard that your brain is your most important sex organ. That's because it controls your sexual response — how your body reacts to arousal, sex, or masturbation. It’s also where your sexual fantasies and identities are.

You can also think of your skin as one big sex organ, with its millions of sensitive nerves. Parts of your body that when touched make you feel aroused are called "erogenous zones." Not everyone has the same erogenous zones, but common ones are breasts and nipples, the anus, neck, lips, mouth, tongue, back, fingers and toes, hands, feet, earlobes, and inner thighs. You get the idea: Any part of your body can be considered sexual depending on how it makes you feel.

Does everyone have the same sexual anatomy?

Everyone's sexual anatomy is a little bit different. Most people have either a penis and scrotum or a vulva, but each person’s genitals are uniquely their own.

When you were born, your doctor probably assigned you a sex — male or female — based on your sex anatomy. But that doesn’t necessarily say anything about your gender identity.

Some people’s assigned sex and gender identity are pretty much the same, or in line with each other. These people are called cisgender. Other people feel that the sex they were assigned at birth doesn’t match their gender identity. So, for example, a person could be born with a penis, but identify as female. These people often call themselves transgender or trans.

Other people have sex anatomies that don’t fit the typical definition of female or male. They may be described as intersex. There are lots of different combinations of body parts and hormones that fall under the intersex umbrella. Being intersex doesn’t necessarily have any connection with a person’s gender identity.
