TW SA/Incest

Hello all, First off-please understand I'm not looking to leave my husband. We've been together for a decade and have a family together. He's a fantastic and supportive man who has never laid a hand on me, or anyone else, who didn't want it. I'm hoping you men can help me understand the draw of his porn choices, and normalize it a little bit in my brain.

And yes, I know the obvious answer would be to ask him. But as you read on, please empathize that this could be very sensitive and he'd likely be embarrassed about being found out. I don't want to bring it up unless it becomes something my mind festeres over and I need more answers.

Yesterday I saw my husband's porn watch history. I do this every once in a while, mostly out of curiosity to see what he's into these days, and potentially to bring a fantasy into the bedroom. I'm very open about what I'm into, even if I'm a little shy talking about it and I have nothing against anyone using porn.

Usually it's kind of different...but manageable. Obscenely large boobs, tiny females with a male partner who has a giant dick, a lot of hentai.

Yesterday though..yesterday was kind of morbid and please note the R word will be coming up soon so please don't read if you're triggered by SA.

I flicked through dozens of meme like photos with captions, and caption gifs. PLEASE NOTE None of these women were under age. There was lots of father/daughter incest sometimes with the mom involved, or an aunt. "dad waited until she was of age then fucks her with all his coworkers because she was always a little bitch", "Dad rapes daughter while mom watches and plays with herself"

Then there was "snuff" porn.

Basically someone took pics of women who were limp or had their eyes closed and followed a similar trend of "I/someone killed her and then I used her body". There were no actually dead women I remember two. One was a view of a woman from behind who was flopped over the side of the bath tub "drowned" and another where someone edited in a bullet wound to her forehead and said something like "she didn't want to suck my cock so I shot her and fucked her mouth"

I'm just really unsettled now. Our marriage has been going really well as of late and we've been having a lot of fun in the bedroom. He's never brought up trying any of these scenarios to me. Could this just be an exaduration of a degradation kink? They seem to all follow that tone. He watches a lot of porn so is it just getting extreme because of being numbed out? Is this kind of stuff common for men, and I'm being a bit sensitive because it's something I as a female would never consider arousing?

I'm not here to kink shame anyone...I really just want to understand so I can move on.
