Yes. I am almost 100% sure.
Yes. The age of consent is 18 and she is a minor dating an adult male. He can be arrested for rape and serve jail time.
Yes.
Not sure about Pennsylvania But elsewhere Its fine.
Yes, any physical contact with you would put him in jail!
There are no laws about dating.
Yes, an 18 Year old Male is able to date a 15 Year old Female. There is nothing that the New York State Law says that you can't "Date", but on the other hand, if you have "SEX" then that's a completely different issue. You will go to jail for Statuary Rape.
No. Jail will come only if they are sexually active with one another and the parent(s) of the underage person press charges against the older person. If they are only dating then there is no grounds for an arrest. The parents may file a restraining order if desired to stop the dating of the two.
Not unless sex was happening before emancipation but with the close age difference it is very unlikely. Dating without sex has no offence in law.
Dating has no laws associated with it. But any sexual contact with a 12 year old will result in criminal charges. Laws and the penalties will depend on the state. And a 7 year difference for someone that young will be pretty ugly.
No Simple There is nothing wrong in dating at this age if the parents are ok about it as long as they do not do anything sexual at all. The 14-year-old would not go to jail if he sexually assaulted her but he could be placed into care depending on his previous history.
Hopefully. He or she is a neophyte at the dating game, stupid or an amateur pedophile.
Yes.
