I was pretty sure the age of consent was 17 in Illinois and that one could not engage in selling sex (porn, etc.) until age 18. A person in Illinois cannot give out nudes until age 18. If you two had sex before you turned 17-year-old, then yes. However, such would be dependent on some kind of evidence, such as your testimony or witness testimony. Because, otherwise, any evidence of you having sex with him would be considered illegal evidence. So, if there was sexual contact prior to age 17, then it may be difficult to put him on a sex offender list. If that happened, I really suggest you walk away from the guy and consider the effects such a relationship may have had on your psychology and view of relationships.
