21 should be the age for porn. Then you can weed out the girls who are underage. And you will also weed out the girls who are in porn for the quick cash and then leave in months. Instead of the women who want porn as a career. It might also help the state of the industry. There are too many girls out there. Spend the time and money building a career for a girl who wants to be here instead of someone who will leave you hanging in a matter of weeks or months.
And it will also get rid of any girl who says she was forced into porn by her pimp or a girl who was too young and "didn't know" what she was doing. Give her until she's 21 and she might change her mind and never get into porn.
