Little kids should have sex. Some of the cartoons in porn magazines show kids sometimes asking or being asked for sex. The message of the pictures and cartoons is that adults having sex with kids is normal. Illegal sex is fun. It suggests that you can't enjoy sex if it isn't weird, illegal or dangerous.
Prostitution is glamorous.
Porn paints an exciting picture of prostitution. But, many prostitutes are runaways, girls trapped in a life of slavery, many having been sexually abused. Some of them are infected with incurable sexually transmitted diseases that are highly contagious, and they often die very young. Pornography makes a profit from the ruined lives of young women. Sex has no consequences.
