I actually think that porn can have a detrimental effect on people, not permanent, but also not always the best. Will government regulation fix it? No. Kids now are having less sex, they are more isolated, and males are now having way less sex in general, so what fills in the place? Porn. If you get rid of porn and not have any changes in society, they will not magically go away.
