Can a 17 year old boy go to jail for having consensual sex with a 14 year old girl in new York state? ?

The girls mother is not pressing charges and the cops were saying how nice the boy is and the girls mom even said she doesn't want him to go to jail and the boy told the complete truth. What are his chances for going to jail, and how long would he have to to go for? The girl gave complete consent and they had been dating. Thank you
