Is it normal i do not understand why they always have sex publicly in films?

Every time I see a romance movie they always doing it in a meadow, or the beach or that sort of nonsense. I understand it is suppose to be romantic but you are outside. What if some random old person walks in and just like "Oh dear lord! What are you doing!" or like what if someone calls the cops since they walk over to see two people naked in the middle of the woods. That’s so indecent! Its also very reckless. Its not like giving them a handy or something its full out butt naked in a meadow. That just seems stupid in my opinion. Why would people be so reckless! If you go to jail for having sex in the nude you are first off put on the SEXOFFENDER list and second might get raped in prison.
