I think porn should not be publicized.It damages moral values.It is disrupting family structure as well.And it's true that it is far more than drug addiction and if once you are addicted you need more ways and techniques to solve your internal frustration and addictory problems.And the product of this frustration is even more disgraceful bukkake is one of them.Sex should be permitted only after marriage.As it's allowed in various religions like christanity;islam etc.
