Incest porn, your opinions? [Trigger warning added by MNHQ]

[Advicelost]

This exactly.

I've had past relationships where the partner watched porn, not too often and as part of a healthy sexual relationship.

Now though I'm in a long term relationship with a man who admitted 16 months in to it that he loved incest porn: he watches mum son porn a lot, I have seen. He also wants to role play "with words only", such as pretending he is my father
I am disgusted by this and totally at my wits end.
He assures me it's just during sex: so wouldn't affect our own kids, but really it's just something I'm so confused by.

Do I tell/ask him that it stop forever as it repulses me. Or do I end the relationship. Our relationship has many other issues but I want this one to be discussed first.

Opinions please. Thank you.

(I am in my late twenties, no kids)

If only!

I've only read the first page, so I don't know whether this thread has changed tact throughout the course of the following pages,

OP, you may be depressed and you may feel like shit, you might even feel like you might happily accept anyone or anything at this moment in time, but please leave him. It seems like he very much has his own issues, and at this moment in time you are vulnerable and you do not need to deal with this.
There are various studies that prove people start watching porn, which often goes from quite mild, to worsening severity as the habit gets worse,
I am inclined to believe these studies, I am also inclined to believe that with watching incest porn, that is either very close to or crosses over into child pornogrophy.
I actually read the book about Shannon Matthews, and her stepfather was arrested for having child pornogrophy on his computer, one of the search terms that often occurs (as it said in the book) was for incest, that along with the fact that about 90% of children are abused by family members and close friends, would make me worry about the statistics of him having viewed something of that nature.

I agree with everyone else, but I do feel sad that you feel bad enough about yourself that you are questioning whether it's ok to be with someone who likes that.... And if you do stay. Do not have children with or around this man.

This issue is enough to run a mile. But I also noticed "Our relationship has many other issues but I want this one to be discussed first."
Why this one? Is it the one that bothers you the most? What are the other issues? If you give us the whole context we'll be able to advise much better.
