Giant boy sites are rare, I have been following my intrests from the time I got my first computer almost thirty years ago. Even rarer than Giant boys is Giant Boy videos. A few you tube efforts, but still rare. Many giant boy sites have come and gone, Giant Kids and Teens was an early forum, it turned into "Giant Teens" When I started,Giantess's reigned, with a small number of Giant men sites, blatantly gay. "Kids" in the microphile community, was a dirty word.
There are more giant children followers then ever before thanks to Giant Boys Zone; a handful of practitioners in the craft survive, their works are found at sites like Deviant Art.
