So long as there is no order restraining the adult from associating with the minor then there should be no problem. If however the parent's or guardian of the minor do not approve of the relationship then they can probably stop you from having contact with that minor.
The boy goes to jail. The girl goes to the hospital.
Yes.
Jail time / Rape
they take him to jail and the girl becomes a stripper
If said girl is a minor in her state, yes.
It depends on the laws of your state.
You can go to jail for that!!
There is absolutely nothing wrong with this. As long as it doesnt become a "love" relationship.
No he will not go to jail, yet the 15 year old girl will be fined for false accusation.
It depends on where you live.
No, Possibly, it depends where they live.
possibly serious jail time, depending on your state's laws, and the girl's parents
