There is a maximum sentence of life imprisonment for rape, assault by penetration, and causing or inciting a child to engage in sexual activity.The age of consent to any form of sexual activity is 16 for both men and women, so that any sexual activity between an adult and someone under 16 is a criminal offence.In most states, the age of consent has been arbitrarily designated by statute.However, this age of consent varies widely from state to state.Voluntary sexual activity with someone younger than 17 is not “consensual” sexual activity as far as Illinois law is concerned.At this age, “consent” is a legal term, not a factual term.
Because there is no such "Romeo and Juliet law" in California, it is possible for two individuals both under the age of 18 who willingly engage in intercourse to both be prosecuted for statutory rape, although this is rare.
To be blunt, a 17 year old boyfriend who touches, for his sexual gratification , the breasts of his 16 year old girlfriend has committed a sex crime, which could put him on the Illinois sex offender registration list.
Actually, any voluntary sexual activity between two 16 year olds could put both of them on the sex offender registration list.
California statutory rape law is violated when a person has consensual sexual intercourse with an individual under age 18 who is not their spouse.
Punishments vary depending on the respective ages of both victim and offender.
