"The lowest age of consent in any US state has been 16 since 2001 (when Hawaii raised it from 14)."
There are probably some lower ages if you account for "Rome and Juliet" laws, aka age gap windows, where 14/17 might be legal but 14/20 wouldn't be.
"Actually the law changed in 2015, after decades of lobbying by rape victim advocates. Any act of nonconsensual penetration is now illegal."
