Sexualization is when people use things that are not meant to be sexual in a way that makes them seem sexy or seductive. Imagine you have a toy car and you use it to make pretend races with your friends. That's what the toy was made for and it's innocent fun. But if someone uses the toy car to make it seem like it's driving on someone's body parts in a way that's sexual, that's sexualization.
Sometimes, people can sexualize things like clothes, music, and movies. For example, if someone wears clothes that show a lot of skin in a way that's meant to attract other people's attention, that's sexualization. When people sexualize things, it can send a message that the most important thing about someone else is how they look or how sexy they are, instead of paying attention to who they are as a person. This can make people feel uncomfortable, objectified, or disrespected.
It's important to understand that there's nothing wrong with feeling or expressing your own sexuality. However, it's not okay to force your sexuality on others or to make them feel uncomfortable because of it. It's important to respect people's boundaries and to treat them with kindness, no matter what they look like, what they wear, or how they identify.
