In Illinois, there is a limited Romeo and Juliet exemption for criminal sexual abuse. The conduct is still illegal, but someone protected by this exception will face the possibility of smaller fines and reduced jail time than someone who is charged with felony sexual assault or abuse.

Can an 18 year old date a 16 year old in Illinois?

The statutory rape laws, or the age of consent laws, in Illinois revolve around the presumption that anyone under the age of 17 cannot consent to sexual acts. For example, an 18-year-old high school senior having sexual relations with a 16-year-old high school junior could be found guilty of criminal sexual abuse.
