The age of consent under Tennessee Law is eighteen (18).
In Tennessee, adults can only have sexual relations with other adults.
A 12 or 13 year old can consent to sexual activity with a partner as long as the partner is less than two years older and there is no relationship of trust, authority or dependency or any other exploitation of the young person.
This means that if the partner is 2 years or older than the 12 or 13 year old, any sexual activity is a criminal offence.
Note that this mans if you are 13 years or younger, you cannot legally consent, regardless of whether the other person is the same age or not.The law exist because the Government doesn’t want any child above or even below the accepted age to be exploited by an adult.Many teenagers first become sexually active before the age of 17. If you are having sex at 15 or 16, are you breaking the law? Sexual relations which occur between adults and teenagers under 18 are left in a legal gray area: laws against corruption of minors as well as estupro laws can be applied to such acts, at the discretion of the prosecution. Typically, Mexican states have a "primary" age of consent (which may be as low as 12), and sexual conduct with persons below that age is always illegal.
