The significance could be to challenge gender norms. By having boys involved with something like tampons, it shows that these products are not exclusive to one gender in terms of understanding. It can also be about education, teaching boys about a part of female physiology and hygiene.
Well, it might be significant in promoting empathy. If boys are part of a story related to tampons, they can better understand the experiences and challenges that girls face. It could also be a way to start conversations about gender equality in areas that are often overlooked, like the stigma around feminine hygiene products. Maybe it's a story that aims to make tampons and related topics more normal and acceptable for everyone, regardless of gender.
