No. Fanfiction that involves such inappropriate and sexual content is not acceptable in the Harry Potter fandom. The Harry Potter series is mainly aimed at a wide range of audiences including children and young adults, and this kind of content goes against the spirit of the original work which is about magic, friendship, and heroism.
It can be very off - putting to a large number of fans. The Harry Potter community is made up of people of all ages and backgrounds who come together to celebrate the magic and positive values of the series. Such inappropriate fanfiction can make the community seem less family - friendly and drive away fans who don't want to be associated with that kind of content.
Yes, there are numerous appropriate 'Harry Potter' fanfictions. For example, those that focus on Harry's adventures in new magical places not mentioned in the original books, or ones that explore the relationships between the characters in a platonic and positive way, like the story of Hermione starting a new magical study group at Hogwarts.
Not at all. Fanfiction should be a creative way to expand on the existing world of a story in a way that is consistent with its values. Sexual content has no place in the Harry Potter universe, and such fanfiction would likely make many fans uncomfortable and is not in line with the ethical standards of the fandom.
One good topic is exploring the different houses at Hogwarts in more depth. You could have a fanfic that shows how students from different houses interact and learn from each other. For example, a Slytherin and a Gryffindor teaming up for a magical challenge.
One ethical issue is that it can be considered a form of objectification. By focusing on a sexual aspect in this way, it reduces the character to a mere sexual object rather than a fully developed fictional entity with various qualities.
Writing about sexual arousal in a detailed and explicit way in fanfiction is generally not appropriate as it often violates ethical and moral guidelines, not to mention it may be against the rules of the platform where it is hosted.
Well, Harry could marry one of the veelas. Given their beauty and allure, it would add an interesting dynamic to the story. Their relationship could involve Harry having to deal with the jealousy of other wizards and also the cultural differences of the veelas. Or he could marry a descendant of one of the founders of Hogwarts. This would tie in a lot of Hogwarts history into their relationship, and their wedding could be a grand event that unites different factions within the wizarding community who have ties to the founders.
Maybe Dumbledore, if he were still alive in the fanfiction. Dumbledore was highly respected and had a great influence. Knighting Harry would be a way for him to publicly recognize Harry's achievements and heroism on a grand scale.
