What is the connection between horses and girls in comics?

Not much, usually. Horses and Jotaro don't have a direct or common connection in most comics.

Well, sometimes in TF comics, horses might be used as a symbol of power or speed, or they could be part of a fantasy setting.

I don't think there's much of a connection. Sonic comics revolve around Sonic and his friends' escapades, and horses aren't a common element in them.

Well, sometimes machines are part of the girl's adventures or help her solve problems.

In most cases, no. Girls have a wide range of hobbies and pursuits, and porn comics are not a common or appropriate part of them. Such a connection would be unusual and potentially inappropriate.

Perhaps it's part of a fantasy or fictional concept where the caricatured horses and women have some sort of interaction or relationship that's unique to the creator's imagination.

Well, the connection could be that comics with girls sometimes explore the various forms of love, like friendship or self-love. Also, the characters' love interests can drive the plot forward.

Harvey Comics and Harvey Girls might not have a direct connection. Harvey Comics typically focus on various fictional characters and storylines, while Harvey Girls were waitresses in restaurants during a specific period.

Maybe Dreamworld Comics has a story arc related to Squirel Girls or they might have some sort of collaboration. But I don't have exact details.

I'm not really sure. Maybe they're related in some artistic or historical context, but I don't have a definite answer.
