Can a 19 year old boy go to jail for being with a 16 year old girl?
Assumption - There is more than just holding hands going on.
The law varies from state to state. Each state has legislated an "Age of Consent" that varies from 16 to 18. So a 16 year old and a 19 year old might not be a problem at all. In other states consummation of the relationship could be considered statutory rape. In still others there is an age difference consideration, meaning if they couple are within a specified number of years of age, there will be lessor or even no charges.
how about if your in florida?
