i would have to disagree. it depends on your system of moral. there are different reason that it's wrong and right. two exampls:: prominent faminists have taken two different approach to this exact question. the kantian would say it's wrong in it's lack of equality and thus to solve it, one needs to have porn in which the girl has as much fun/control as the guy. On the other hand, there are people who argue it's wrong for both GUY and Girls as porn potrays sexuality in an extreme which in effect alienates both the man and the woman as the man now has to "perform" while the girl has to "receive". that's just the fundemental.. i'll find the two articles later. the point is, wrongness/sins are defined by different moral standards that have changed over time and i believe in this highly individualistic society, one has the right to choose ones own standard as long as a general utilitarian balance exists. even if marx would disagree with porn, aristotle's writing indicates porn just might be all right
in conclusion, i want boobie.
