Similarly wobbly views on sex and adolescentsâor rather sex with adolescentsâare on profligate historical display elsewhere. It goes in the opposite direction, too. The age of consent in 1920s Chile was 20, but now it's 16. A century ago in Italy, it was 16, too. But today it's 14 there.
The age of consent -- the age at which a person can legally give consent to a sexual partner -- varies from 14 to 18. All states which place the age of consent younger than 16 years of age have provisions that differentiate between an adult sexual partner and a minor sexual partner. It is not legal anywhere in the U.S. for an adult -- 18 or older -- to have sexual contact with someone younger than 16. Some states consider the age difference between a teen and her sexual partner, both in determining whether a law has been broken and in determining how severe the charges should be.
