17 F here. I've been talking to a guy I met online. He's 30 & said he wants to have sex with me. He keeps trying to bribe me with gifts. I think a lot of this seems suspicious. I don't know if I should. I need advice from an adult please?

Delete all and move on.

You have no idea who you are really talking too.  A man of 30 talking trash to a young girl is just wrong. Please stop!!

Your gut is telling you something is not right about this, or you wouldn't be on here asking. Listen to your gut! You have instincts for a reason. Use them! This guy is most likely a predator. You need to cut all ties from him and move on, quickly! 

First of all . . . I am guess 17 F means your 17 years old . . .

If he says he is 30, he is most likely 40 . . . . Also, depending on the state the "Act" would be done . . . It is statutory rape and could not only get him jail time but a life branded as a "Sexual Predator" of which he seems to "Fit the Bill" . . .

All that being said, the fact that you want "adults" to weigh in on this decision means that you have:

1. No cognitive ability to understand the full weight or measure of the consequences of such actions
2. Most likely are posting as a way of Bragging

Delete you account on whatever internet communications you have with this person . . DO NOT send pictures of yourself, or give him any information (school you attend, phone number, heck even zip code) about yourself.

This is a huge problem. You are still a minor. The fact that he knows this and is still pursuing you lets you know he is mentally unstable. Have you talked to your parents. They are the ones who you should tell. They love you most in the world. Take action fast and delete or block him NOW!!!

PLESE DO NOT MEET HIM. OR HAVE SEX WITH HIM. I repeat DO NOT! Abort mission, honey!!!!!!! This is dangerous land here! DELETE HIM AND FORGET ABOUT HIM. Do not give him any information. Oh my god what is going on with the world.
