18 years old should still be a learning age. It's a little early to find a boyfriend, but it's good to have your own plans for these things. Don't care too much about what others say and want you to do.

Sometimes people joke. Maybe when you grow up or look good, you will think it's time to be a girlfriend. It's just that some people joke moderately and some people are open-minded, but in the end, you still have to grasp it yourself and don't care too much about what others say.
