Is it Zina of heart/haram to read about same gender without explicit scenes Zina?

I read ,or let's say I write stories about two men loving each other. These stories do not contain any explicit scenes and the focus is not at all on sexual points and in reality I myself am not at all attracted to the same gender but I am really really addicted to writing and imagining these stories without sharing them with others. Is the sheer topic of them being the same gender haram? Is reading/writing these stories considered Zina of heart/eyes?
