Is it normal i come up with stories in my head

I don't do that but it sounds great, seriously, that's really nice:)

I have an entire living world fleshed out in my head, every detail from its government, to the characters looks and personalities, I even get minor news updates via one of the residents, she reports goings on, whether scientific updates, new historical discoveries, government news, or on how the postal worker got her head stuck in the mailbox somehow.
Even sexual escapades from locals are sometimes discussed.

Nothing wrong with imagining stories in your head, its fun! I enjoy reading as I can see the story come to life in my head in vivid detail. Now, I admit it is probably less normal for someone to have an entire living world fleshed out in their head, but it's enjoyable.

And good gay stories?

I enjoy having daydreams about my favorite fictional characters. There really isn't any ongoing story; I just like having them sort of hang out in my mind-space, like imaginary friends. Don't know if it's the same thing as what the OP does but that's what their post reminded me of.

I do it a lot also. Mine aren't as super detailed as yours are but they do have sequels. Plus the characters are usually either my friends or the people around me at the moment. I was wondering if anyone else did that lol.

I kind of do that. But usually mine are short and not ongoing. But i assume it's normal haha

I do it too,, but it's really just one story that i keep adding to, because it's very long and i haven't quite finished it yet..it's sort of like a fantasy world too.i doubt i'll ever write it down, maybe it only makes sense in my head. i have drawn the characters though.. do you do anything with your stories?
