Answer:
Actually, according to the wording of the Statute, if you are 16-yrs-old, a sexual relationship with someone 24 or older is not legal in the state of Florida.
Florida Statute 794.05
(1) A person 24 years of age or older who engages in sexual activity with a person 16 or 17 years of age commits a felony of the second degree.
The key in the above Statute is that it says "24 years of age or older." The wording of the Statute includes the age of 24 in those who commit a felony if they engage in sex with a 16 or 17-year-old.
