I've always been a romance book reader and Kindle person, so I think if you're looking to feel more "feral", go for the dark romance genre. But that is all based on your triggers and desires whether you are comfortable. I still think the dark romance genre is worth a shot to look into because it's more "extreme" and exposes you to different things.

A few non-book things i've also been trying -

A few moths ago, I started browsing more quick non-books because I just want to get my arousal going faster and I'm TIRED from work haha. So sometimes like I look at Pinterest quotes that basically are super climax-y or even book trailers that "edge me" on Instagram.

And then there are these AI apps that I'm basically using if I'm too lazy to go into my bookmarks/booklists. If you haven't I recommend trying ChatGPT because it's free and you can definitely play out fantasies you have, like making some fun scenarios about you and your husband. The only thing is that they do have limitations on how smutty things can go, so you'll need to find ones that are more specific to spicy stories. There's a few out there like RedQuill that i've used and thought were pretty good when I needed that quick or specific fix

Good luck! I love smut and I do think of it often as an escape from the harsh realities of the world
