I encouraged my 16-year-old daughter to get a job at a strip club
I am pretty sure that that is against the law!
Oh that's not true, she asked for my permission first.
I still think that is illegal, whether or not they have your permission. You should not encourage someone that young to get into the adult entertainment industry.
It's her choice. If she wants to be in porn then she can.
I would think that you would want your daughter to grow up and be successful. By encouraging her to go down that path, she may end up being abused or worse.
