How do I help my teen daughter understand why porn is bad?

[Pina]

I understand your concerns although I disagree with them. I think it's perfectly natural for her to have a curiosity but definately not in the way that she's going about it, especially taking into considerations that nowadays so many colleges and workplaces look at all your online history, including Facebook and they can get acess to things that have been deleted. I think you should tell her your views, that you don't agree with her watching those videos but you cannot stop her from doing that on her own. Then tell her that she needs to remove the videos from her wall and if she refuses or does it again then delete those certain friends, then if it happens again delete her facebook.
If you just immediately shut off the internet or whatever she'll most likely rebel. She also probably thinks that what she's doing is mature, in more ways than one. Saying that she doesnt care what other people think is good and bad, because she shouldn't let everyone else influence who she is, to an extent. I think you should tell her that you're proud that she wants to be her own person, and that her not obsessing over what everyone else thinks is a good thing but that she also needs to take into consideration her future and the consequences that could come from doing this.
