For me, it has to be either 'An Unsettling Scent' or 'Minami-kun Wants to be Teased by that Voice'.
'An Unsettling Scent' was cringey at times, like during the sex; it seemed lowkey painful, and the bottom looked like he didn't like it, only for him to say he's into it, and for that whole BDSM aspect to get lost in the sauce as the story progresses. But still, one of my favs I keep hidden from the public... sssshhhhh
'Minami-kun Wants to be Teased by that Voice' was really hard for me to read cuz it relies on the fact that one of them does NSFW ASMR and i find it so cringey and laughed multiple times :p. Though it was really sweet and happy that they matched eachothers freaks :))))

Guys* rec me the most cringe BL you ever read, I'm talking so bad that you ended up actually liking it. Even better if it has comedy in it. (like watching a B-grade movie that's just to good to hate)
