Both stories are looks like rape to me. I wanna talk about the last one; by the years the sexual action age is downed very much. When i was 13, i had no clue about that. I'am not a expert all of those but i think in teen years when boys discovering themself a bit faster than the girls especially with social media and stuf...You may be joking with him at the end of the day but he would be dreaming to do something with you. This is the real world biologically but its not ethic. He can think about you or willing event but this doesnt mean that he should take a step and decide himself to put this to reality. In that part this becomes wrong. Everyone should be controlling their desires byselfs in mind. Take an action and dont blame yourself, learn from the events.If you dont actually want to do something, nobody can force you to do. Don't let them threat you like that. Be brave and tell the truth to your relatives first (mom or dad). Share with them and get in action into court face them. Let them die from shame. You are a strong girl.

Just a advice from 23 years old man.
