You indicated no sex in your title, then mention sex on the description. so, which are you asking?
If you are just dating(no sex of any form), that is probably legal, but keep in mind that you are in your parents' custody, and they also have the right to prevent you. They can also make a great deal of trouble for your BF if they desire to do so.
Talk with your parents to work this out.
