Not unless the parent(s) aided or abetted the action. (In the US) at 18 the 'child' is usually legally emancipated and no longer a 'ward' of their parent/guardian, with the exception of Missouri - 17 years, and Alabama & Nebraska - 19 years, and Mississippi - 21 years.
yes
no because you are considered an adult
No, but you can do it once you turn 18.
You have to be 18 in most states. Unless you are with your parent.
If you have a parent with you, you can do it before 18 years. If no parent, then it's 18 years old.
Nope! At 18 he is an adult and have to take responsibility himself, Even if he stays at home.
You have to be of legal age, 18, unless "if a parent them self" means something that could change that. You need to change the question so we know what you mean they did (if they did something).
If they are under the age of 18, you certainly can. You are responsible for whatever they do while unsupervised.
Dating is not illegal. Sex is. Sex with parental permission is illegal fo the 18 y/o guy and the parents who would be charged with child endangerment.

Can't. The 18 year old is an adult and do what they want.
