Fine, I will answer your questions in a few ways, actually.
Bringing a minor across state lines for sexual purposes is a federal crime punishable by $10,000 and 10 years in prison or both.
Soliciting a minor for a sexual liason (because you are NOT now the age of consent in either state and if you and this mysterious no one have even TALKED about getting naked and sweaty that is solicitation), we get to add another decade.
If your parents KNOW about you crossing state lines for your bumping uglies session, they get get to go to prison, too.
Is THAT clear enough for you?
In the realm of bad ideas, this is up there with lighting a match to see if the gas tank is empty.
