I have a family friend who's 12 years old and she loves haning out with guys my age. Im 17 years old. She has a boyfriend who is 17 but they live far from each other. I called the guy and asked him if he doesn't think she's too young for him and he said no. He also called her and told her that I called him. She's upset that I called and she believes that age doesn't matter. She also doesn't tell guys that she is 12. She tells them that she's 13 or 16.
She is too big for her age and she said that she wanted to have sex with her so called "bf" and she's going to go to his house. What do you think I should do ? Should I stop her?
Tell her father or just leave her alone?

I'd let her parents know what's going on and have another talk with that 17year old friend, only I would not ask him if he thinks she is too young, I'd tell him she is and tell him to leave her alone. He ought to be ashamed of himself.

Tell her dad also call and remind your frined that having sex with a 12 year old sends him to jail. And as noted tell him he is too old, and if need be, tell his parents also.

Tell her parents. This guy is breaking the law and is a PEDOPHILE! At 12 she is nowhere near ready to have sex. How is she planning on going to his house? Is he picking her up, is she taking a bus by herself? Either way it's dangerous.

Has she ever even met this guy in person? Is it someone off the internet? She could end up in a world of trouble with him alone at his house.

She might be mad at you for telling on her. But if you don't, she could regret having sex with this guy for the rest of her life. Her parents need to be told about her behavior. Why is a 12 year old out by herself hooking up with guys anyway? How do they not know where she is at that age?

Please do the right thing and tell her parents. Also give them the phone number and any info you have on this "boyfriend". Someday when she is older, she will appreciate that you did the right thing. You may be the best friend this girl has ever had by telling her parents! Please do so she is safe! She could get pregnant or get AIDS or anything could happen! Age does matter when the person is under 18! This so called boyfriend is a child molester who is taking advantage of her!

Yeah... you're friends with a 17 year old guy who's dating a 12 year old?. I question his judgment... but I also question yours.

Got to remind that 17 year old... having sex with a 12 year old may not be illegal (in some states, it is... in some, not sure), but it def is sick as all hell.

Shanny did not say that she was friends with the 17 year old boy... only the 12 year old girl, that is a family friend.

Ah. Understood. Read too fast. My bad!

I would suggest you talk with a neutral, disinterested third party adult, such as one of your parents or a teacher or school counselor. Let them advise you as to the best course of action to take. I don't think it's appropriate for you to take matters into your own hands.

Hmm, tell her parents, or tell his parents? If they were involved with their kids a little more then this would probably not even be an issue. The parents need to do their job at HOME.

Let both of their parent's know (if you know the guy's parents) The girl's certainly need to know what their daughter is up to, and the boy's father or somebody needs to have a talk with him. What he is doing is wrong and we certainly would not want this to become a pattern with him. (messing with underage girls)

I would have to tell a responsible adult, and let them handle it.Her parent need to know of her behaviour really fast though, and stop letting her hang around you for sure.
