No. Fanfics that involve sexual content, especially gay sex in this case, are not appropriate as they often go against moral and ethical norms, and may also violate the rules of the original work's fandom.
One popular 'boy meets world gay fanfic' might be those that explore the relationship between Cory and Shawn in a different, non - traditional way. For example, some fanfics could focus on a scenario where they realize they have deeper romantic feelings for each other as they grow up. Another could be about a new character introduced into the 'boy meets world' universe who has a gay relationship with one of the main characters.
One negative impact is that it misrepresents the original 'boy meets world' story. The show was about friendship, growth, and family values. Adding gay sex into a fanfic completely changes the tone and message. Also, it can create an uncomfortable environment for those who are not interested in sexual content within the context of this family - friendly show.

I'm not sure specifically about 'gay foot fetish boy meets world fanfic' being popular. Fanfic is a very niche area and often such specific combinations might be hard to find mainstream popularity. However, in the vast world of fanfiction, there could be some works out there that fit this description.
To start writing such a fanfic, you should begin with a clear idea of the story you want to tell. Since it involves 'gay' themes, you need to be sensitive to the LGBTQ+ community's representation. Regarding the 'foot fetish' part, it should be integrated in a way that doesn't overshadow the main plot. For the 'Boy Meets World' aspect, study the show's story arcs and character dynamics. You can start with an outline, deciding on the main events, character relationships, and how the unique elements will fit into the overall story. Remember, writing fanfic is about creativity but also about being appropriate within the context of the original work and the broader community.
One popular 'boy meets world fanfic' could be those that focus on Cory and Topanga's relationship further adventures, like exploring how they handle new challenges in their married life.

There could also be fanfics that rewrite certain episodes with different plot twists to make them more interesting.
Common themes in 'Girl Meets World' gay fanfic often revolve around the idea of alternative love stories. This can include the challenges that gay characters might face in a world that is somewhat similar to the one depicted in the show. It may also involve themes of loyalty and friendship turned into love. For instance, two side characters who were friends in the show could be the focus of a gay love story in the fanfic, exploring how their relationship develops and how they deal with the reactions of other characters in their 'Girl Meets World' universe.
Obviously, Topanga and the boy are the main characters. Since it's about Topanga being pregnant, they will be at the center of the story, dealing with the joys and challenges that come with it.
Writing fanfic that involves sexual content, especially when it involves minors (as characters in 'Girl Meets World' are likely to be young), is inappropriate and unethical. It violates the boundaries of respect for the source material and can be considered a form of exploitation.
