I dunno, as a society we seem to be okay with letting kids watch insanely violent material (you wouldn't believe how many kids I've taught in school have seen Saw, for instance) but we seem to freak out if there's a love scene that's a little explicit.
While we're talking about society and movies/TV... think back to all of those Twilight moms lusting after underage Jacob and that's apparently okay but the folks lusting after teenage Hermonie are weird.
It's apparently no big deal for those 30 year old ladies to oogle a shirtless 17 year old boy but it would be creepy if a guy the same age oogled a 17 year old girl.
Actually, I used to shudder involuntarily when NPR would blindside me in the morning with a "Twilight Mom" interview.
But again, you're starting to frame arguments no one made here, and making comparisons with things that aren't remotely the same, like conflating someone thinking a writer and artist choosing to put a 14 yr old character in fetishwear is a tasteless choice for them to have made with not liking love scenes in movies.
Every visual, every image, in a comic book is deliberate and designed, and the OP is in a sense asking what intended purpose this image served if not sexualization.
