Sexual desire is what makes us feel attracted to people in a special way. It's a feeling we get inside our body that makes us want to do "sexy" things with another person.
Sometimes, our bodies can feel a little tingly or warm when we see someone we find attractive. This feeling can make our hearts beat faster, or we might suddenly feel like we need to breathe more deeply. Sometimes, we might even feel a little bit nervous or scared – but that's okay!
Sexual desire can be caused by all sorts of things, like seeing or hearing something that we find exciting or romantic. Sometimes, we might even have dreams about doing sexy things with other people.
It's important to remember that everyone feels sexual desire in different ways, and nobody's way of feeling is better or worse than someone else's. We should always treat other people with respect, and only do things we feel comfortable with.
