What are the consequences if an 21-year-old gets a 16-year-old pregnant?
It all depends where you live. In usa many states have a consent age of 18 so if you live in one of these you could be charged with statutory rape which means you could go to prison for sex offending. You really need to check on these laws for where you live. If you live in Britain then you have nothing to worry about from the law as the consent age there is 16.
