I never said they were facts; I simply said that they were myths - that may make them facts to one person, opinions to another. I was simply stating what people think of when they think about "porn apologists".
So, Springchicken, if her DP's use of porn makes her feel the same way as she would were he shagging someone else, a compromise would be agreeing that he shags other people discreetly, does not ignore her in order to shag someone else and does not (for instance) leave his "shaggee" in full view in a shared environment with his partner or where the shaggee might be chanced on by someone else ... 
Your compromise does not address the fact that it is his actual use of porn that bothers her, not simply the fact that she caught him at it.
The fact that you are male or female makes no difference to me, LostMyIdentity. Each time you view porn, you do so with the knowledge that you may be complicit in the trafficking, exploitation or abuse of another person, be that person male or female. Another MNetter put it far better than I ever could when she said she wished that there was a warning message to pornographic material which people would have to click on to signify what it is they are consenting to view, along the lines of :
?You have chosen to view pornography. Your actions could be directly facilitating the abuse of the people shown in this and other pornographic material. The producers of pornography claim that all the people appearing in pornography will have done so by their own free choice. You cannot verify those claims. The producers of this pornography could be lying to you. You may be about to view real abuse happening to real human beings. Do you wish to continue??
Anyway, I am starting to do what I promised I would try not to do, which is turn this into a pitchfork battle of porn VS no porn. To the OP, you need to decide what parameters you are comfortable with (if any) when it comes to your DP's use of porn, but my advice would be such parameters shouldn't really involve lies or deceit, either him lying about his use of porn porn or you lying that you are fine with him using porn.
