ELI5: Explain Like I'm 5

Human sexual behavior

Human sexual behavior is how people behave and express themselves in a way that feels good sexually. This can involve touching or kissing someone you like, and it can also involve wanting to have sex with them.

When two people like each other, they might hug or hold hands because it feels good. They could also kiss, which involves moving your lips against someone else's in a nice and gentle way.

When two people really like each other, they might want to have sex. Sex is when a man's penis goes into a woman's vagina, and they move together in a way that feels good. This can sometimes result in making a baby, so it's important for adults to make sure they are ready to have a baby before having sex.

Everyone is different when it comes to their sexual behavior. Some people like to have sex with people of the opposite sex, some like to have sex with people of the same sex, and some don't want to have sex with anyone at all. It's important for people to respect each other's choices and not judge them based on who they like or what they want to do sexually.
