It depends on the specific situation and the character's personality. Some heroes might have moments of fear but overcome them through their determination and sense of duty.
Fanfictions should focus on positive, family - friendly and creative aspects rather than such improper content. So I won't discuss this particular one.
Look for fanfic communities dedicated to MHA. Sometimes, they have specific sections or tags for more unique or educational - themed fanfics. You could also try reaching out to other MHA fans and ask if they know of any such fanfics. But always be cautious about the content you might encounter.
There might be some fan - fictions that touch on themes related to sex education in the context of the MHA world in an appropriate way. For example, it could be about how the characters learn about relationships, respect, and boundaries which are aspects of sex ed. However, it's important to note that such fanfics should be in line with the general ethical and moral standards of the fandom.
To some extent, it is popular. There are many online platforms where MHA adult fanfiction can be found. The popularity might stem from the fact that the MHA world has a rich cast of characters and a complex universe. Fans who enjoy adult - oriented storytelling might use these characters to create their own narratives that are more in line with their interests in terms of relationships, power dynamics, and personal growth, all with an adult twist.
