In general I don't like humiliation content or blatant ego-stroking content and these two are flip-sides of each other. The whole idea that having this huge donk is the source of your pride, that the dick itself is a literal measuring stick for masculinity, and having it taken away is the most humiliating thing that could happen is just so...well, it's really the silliest aspect of a guy's mindset. Most any content that caters to the idea, whether it's bimbos salivating over it or bitches going on about its inadequacy, just comes off as so very insecure. This is something that has its thumbs in many pies, too, and it's far more pathetic to see a guy who can't handle it if a trap's dick is bigger than theirs or something than it is to just have a smaller penis.
The whole reason I don't tend to like either variety of this content is precisely because the basis of what should be humiliating/a source of pride is usually so banal and the further it goes into the whole big-dicked bull/small-dicked bitch thing the more deranged and shallow it seems. I'd say it only works consistently well when the target is clearly a shallow sod and have done enough to warrant a taste of their own medicine. But most small penis humiliation scenes that I've seen are basically just eroticisizing a man's feelings of inadequacy and I feel that content that builds up the ego without reliance on banalities like penis size is ultimately healthier for someone than getting off to the idea that they're literally not measuring up.
This is a funny anecdote I like to tell: I've been friends with this girl for a long time, back to secondary, and the ex she ends up stacking her new boyfriends against is the one who had the smallest dangle. I've no idea if she's exaggerating for effect but according to her it was no bigger than her pointer but he was so in tune with her body and would ram it right into the best spots that going back to boys who would just pump away was like losing a favorite dessert forever. And when she'd get cheesed off a them she'd tell them to their face that they were less of a man than old babydick Ryan. It's always a thing to watch just because you can tell that the whole idea goes against everything they believe and it bothers them immensely.
If there's any style of it I like it's that, where someone who was sure they were a stud suddenly feels inadequate.
