You shot me down I was about to recommend a flowerxboy story
Well even if you don't read it I want to talk about a very funny scene in a novel (humanxfish) the fish can transform (fish, human, merman and fish head with human legs ←(*꒪ヮ꒪*)
In a moment of grave danger for his boyfriend, the fish is the only one who can save him but for that he has to run with the fish head form in the middle of the night and obviously he was seeing by people (≧∀≦)
Now about those wild recommendations I'll come back
I used Traumatic as a tag and found this
https://www.mangago.me/read-manga/placebo_yaoi/ the above comment is absolutely right if everything is like this I was traumated and I didn't even read it I just looked at the photos
Now things I have actually read
https://www.mangago.me/read-manga/what_it_means_to_be_you/
https://www.mangago.me/read-manga/the_villain_s_savior/

Yeah....i knowww ╥﹏╥ i have aphantasia so I don't have mental images and I don't dream so I just take one for the team I guess..... I read eroguro almost like a social experiment? Just to see how FAR human imagination can go. This list doesn't even have some of the top worse things I've read since they're not on mangago but these are still fucked up ╥﹏╥

Recommend me some WILD stories, interpret that however you want. Traumatise me, have me in shock, frustrate me to no end, I'm up for anything considered wild.
But no beastiality, that's too wild for my liking
