<human>: Condense the text into a few key points

So, he says he doesn't want to have sex with a family member or anything, he just likes the forbiddeness of it. He likes to read stories about incest (quite a lot) and he likes to roll play with it.

This freaks me out. I've been doing my best to go along with it and keep an open mind, but I just don't know how long I can keep up with it. 

When we roll play, me pretending to me his mom or him pretending to be my dad, it just kills the mood for me. I get a flash of their faces in my head and it just feels awkward and wrong. 

I feel horrible about this because I don't ever want him to feel ashamed or that he can't tell me about these kinds of things. I want him to feel safe and comfortable with sharing with me sensitive information like this. 

I want to make it clear that I love this man dearly, and I would never leave him because of this. But it makes me highly uncomfortable. I feel like, what if he does have sexual feelings for a family member but he is just afraid to tell me? 

So, what I'm asking is, what can I do to make this more enjoyable for me? I've read some stories and it just grosses me out and I am usually unable to finish them. And I find it pretty weird that my husband can read them and then be aroused by them. But I want to make him happy, keep him satisfied and show him that he can be comfortable with me doing this. Am I over thinking things? Should I not be worried about him finding family members sexually attractive? Also, I really want to understand what is so appealing about incest. Educate me please.
<bot>: My husband is into incest. This freaks me out but I want to be more open about it and maybe learn to enjoy roll playing with it.
