Does Incest SE*x Exists..?

I think it really happens, it was on the news maybe once or twice ...a brother and a sister were 'in love'...they were living together and everything..

I am sure that is does exist in one way or another in this world. It could happen through the people's own fault or sometimes it could happen through no fault of their own. Like if someone has a close relative, that they did not know they had, I guess this could be something that is not an intentional thing, and although I do not know of anyone like this, I am sure that in this world there are people who do it.

Well depends on how you look at it. In the past, certain society (those I know are Japan and Rome) believe the bloodline is better the others, so the marry between families and well the do not look at it as incest just ensure good genes.

It sure does but it's hidden from public and probably forced in most cases.

I do think it exists except it's very taboo.

It do exist. i hv heard frm someone, bro sis went somewhere and had to sleep on the same bed then, started fondling each other and.. So it exists but very rare. As it is not acceptable in society, people try to hide it at every cost.

Yes, it does But there's no way that people would reveal it in public because they knew they're going exposed themselves and tell the story because it's still and will not be accept by our society.
