Question: Are statutory rape laws proper? Statutory rape laws criminalize seemingly consensual sex when at least one party is below the age of consent, but sexually mature, e.g. when an 18 year old has sex with a 15 year old. Are such laws proper? Should the over-age person be convicted if he or she didn't know (or couldn't reasonably know) that the under-age person was under-age? What if the under-age person lied about his or her age? What, if anything, should happen legally when both parties are under-age, e.g. when two 15 year olds have sex?

Question: What constitutes consent in sex? Can a person give tacit consent by his or her actions? Is explicit consent required for some sex acts? Once consent has been given, when and how can a person withdraw that consent? Does the legal perspective on these questions differ from the moral perspective?
