If you are in grade 8 what should you do after you get your first boyfriend?

You are still very young, so nix the sex! If he tries anything with you NEVER be afraid to tell him to stop!!! You'd be a smart girl to do this. You could go to movies with him, your favorite hang-outs, go to concerts (if you can afford it) and the both of you could hang out with each other's friends. That's about the norm. Hold hands go to the movies and thank your parents for driving you.
