> Watching pornography of normal acts with male or female anatomy I doubt will cause issues

It's not that simple. Not only is there habituation, but sex is something the brain reacts pretty strongly to. It can't be that neutral.

There are also the ethics of how porn is created - basically prostitution with a camera. And the social aspects of it all : intimacy as something banal, available at any time, completely separated from actual human relationships, and marketable.
