Under Illinois law, the age of consent for any type of sexual activity is, typically, 17 years. This means anyone younger than 17 years of age cannot lawfully consent to any type of sex act involving sexual conduct. Sexual conduct is the touching of any sex organ of another.

Can a 28 year old date a 17 year old in Illinois?

Illinois statutory rape law is violated when a person has consensual sexual intercourse with an individual under age 17. However, if the offender is in a position of authority or trust over the victim, the age of consent is raised to 18. Illinois does not have a close-in-age exemption.
