That's why there are many stories of couples who are unknowingly siblings maybe adopted or separated from birth or half siblings. It's growing up together or knowing that disrupts this attraction
That last part is the basis for genetic sexual attraction, which is also some interesting stuff.

It kind of bothers me personally because I have a bunch of half siblings I didn't know most of my life ahaha.

But you should really check it back on all the double posts. If you have more to add just click edit and add it.
