is it wrong for a 16 year old dating a 30 year old ?
First of all In 12 U.S. states, a person can't legally consent to sex until age 17, that is one issue.
Further, teenage brains are still in the process of developing until age 19 or 20. Before that, your ability ability to consider and use judgment is impaired.
On a final note, what could u two possibly have in common?
Try to imagine that age 5 years form now. How does it sounds? You can have fun but nothing serious. Or you can go online dating like Tinder, or ask people there, find someone near your age. Oh, and also you can check this one www.partyline.com. My friends are using that one. Good luck! ;)
