The UK's new porn censorship system doubles as a surveillance system that will study each person's tastes.

Today's typical porn gives teenagers misleading and/or unhelpful ideas about sex. Rather than making them work harder to get access to porn, it would be better to do some social engineering that would lead them to porn that would show sex that is more realistic, pleases women as well as men, and includes relationships.

(Defining "porn" to exclude such videos is counterproductive, unless censorship and repression are your goals.)
