Haven't read all of the thread, but the 18 year mark is bullshit. Biologically, a child becomes an adult/sexually mature at puberty. Emotional and mental maturity varies from person to person. An 18 year old can date an emotionally retarded 18 year old with the intellect of a toddler, but can't date a 15 year old who may be wise beyond her years? Certainly, these types of cases shouldn't carry such heavy consequences. Teenagers having consensual sex is not rape or predatory.
