yeah man that´s porn, some of it, but there are different kinds of porn as well... and all porn are not bad. But for a viewer it can be hard to catch what is and what is not, if it is a work of a photographer with good reputation I presume the model and the situation is okey with everyone involved.
The same picture in another context can be a disaster... but whatever, the model cannot be identified so she will probably not even know she´s around the net showing private parts...
Take famous Sally´s picures refered to earlier, if my neighbour took pictures like that he probably had to do time, even in Sweden! In the US he probably never would walk the streets again.
It seems like you and many other consider porn bad, automatically, like it was no matter of discussion. Maybe it is, but I don´t agree.
Probably you scream your heart out when I call some of your work "porn", just because you live in the country of total freedom, there almost everything is tabu. Strange world. But it is not the real world. It´s just America.
