It is legal to date a 21 year old man if you are a 17 year old girl. It is not legal to engage in certain activities with a 21 year old man as he could be prosecuted.
Yes.
It depents on the country you are from
No it is illegal.
if a 20 year old man gets a 17 year old girl pragrant, can their be any legal actions, I can bring agaisnt him.
The first thing to determine is whether it is legal. In most states and countries that is perfectly legal
Yes if you dont use a condom. But a 37 year old man can not get a 13 year old girl pregnant legally. You would have to be 18 or older for it to be legal.
sure as long as everyone is okay with it :)
Running away is not legal in any state. In that case you could just move out.
No because if she is 18 she is a legal adult
No, that is very illegal until you are 18.
