Half of the population takes a penis in his hand serveral times a day. Probably sees it serveral times a day too. Nifty peeling utensil. What is pornographic about a penis as such?
I wonder the same about female nipples. Apparently they are not safe to be seen for youngsters, while lots of kids sucked them as a baby. Even feeding a baby is seen as obscene. Male nipples are OK.
Porn is about raising sexual tension. Seeing a man in the nude, with dangly bit oncovered does not cause that for me.
If male frontal nudity is seen as worse than female frontal nudity, does that mean people are afraid men could turn gay by watching?
