Florida recognizes a 'Romeo & Juliet' exception to the statutory rape laws, so long as the parties are between 16-23, and both parties consent. Some courts have found that laws prohibiting sexual activity with minors, where both parties are minors, violate Florida's constitutional right to Privacy. The laws are different in every state, with some states allowing minors to consent to sex as young as 13, and other states requiring all parties to be at least 18. There are many variations in between.
