The first story has the MC having a DNA or something that makes people either extremely drawn to him or hate him, also his sperm cause changes in hi girlfriend(s).
The second story is a westers (not 'Escape From Lexington') has the MC going west to avoid the Civil War. His father advises him to act simpleminded when going into town. He goes West and becomes rich by defeating some thieves and taking their hoard.
I think the first is a series by Crumbly Writer, or something similar name. I think one of them was called "Trying to be Normal".
But I'm not sure of any of it, and I find no sign of that author or title on the site today.
They're still there, since they were never removed, yet they're now archived, so they're not as easily accessible. My Not-Quite Human series, as Tacayo noted.
I wrote several nanobyte stories, where the automated nano-technology augments the character's innate DNA and thus their general biological physiology.
In fact, I'm still using those same story tropes now in several concurrent stories.
But my last story, Nowhere Like Home? (2022) was about recovering the protagonist's lost memories, as it wasn't the sperm itself that changed anyone, it was the associations with the newcomers creating their own links to his own past (a different approach, overall).
I do have my favorite story tropes which I keep using for different stories. In my initial Catalyst series, which even I can hardly remember anymore, it was about someone with unique abilities which others help him to access. So while there are sperm exchanges, it's not the basis of the story, becoming who he was determined to be, is the story.
However, I pulled several stories while planning to rewrite the entire multi-volume series, only they never got off the ground and was subsequently abandoned.
It is possible its Vincent Berg Not Quite Human

The second one could be Dual Writer- Run Away

Thank You.
The second story is correct, but I still have not seen the correct first story.
The first one might be the Catalyst series by https://scifistories.com/a/Vincent_Berg
It's on scifistories.com
He's also here on SOL https://storiesonline.net/a/vincent-berg
The second one looks interesting but I can't remember ever reading it.

To me. this sounds like Lumpy's Destiny's Road and sequels.
