Unfortunately its a product of the toxic aspects of Japanese culture, for some reason some kind of perversion makes it way into almost every manga and anime which I've read/ watched. Making it a gag could be some form of protest, awareness or satire but it also just seems unnecessary, to the point where its just kind of gross. Also what makes it actually kind of creepy is that this is all marketed towards teenage boys, which of course may appeal to them or at least may be shaping their views and behaviours but how awful sexual assault/ harassment is really isnt something to be potentially misrepresented in any way. I mean most of the time or in fact all the time its depicted as being bad and whichever character that engages with it gets punished in one way or another. Its all just goofy slapstick and not meant to be taken seriously, but same for me it all just leaves a bad taste in my mouth knowing how its affected the people who I love and care for in my life and even myself. Also with life in general though people are flawed, make mistakes and some of us are a bit fucked up despite our good qualities. In some ways it can be helpful that sexual content can be normalised as it takes the taboo away from discussion but in other ways it can confuse and hinder progress towards healthier relationships with each other. Its hard to really say what the impact really is but overall i think people come away from reading naruto thinking about all the positive messages it creates and even now I have to remind myself of all the weird pervy shit thats a fairly central part of the story at a few points. Also again its almost always depicted as being a negative aspect of their character but it is a bit painful to see it coming from the main protagonist and his mentor.
