Is It Illegal To Marry Your First Cousin?

Its not really illegal its just unusual

Yes it is pretty much legal. Different countries have different laws but there is no law which prevents first cousin marriage.

But what if you are not planning to have children? Birth defects are only an issue if you plan on reproducing. What if you just love each other and want to spend the rest of your lives together?

I believe it is in most States to marry a cousin as long as it is not your 1st cousin.
Why don't you try to Google that question. You might find an answer
there. You may even find explanations, both Civil and religious.
Different religions may have varied views on the subject, especially if
you you intend to marry your cousin.

It's perfectly legal in most countries and about half of US states. Offspring have a very slightly elevated risk of genetic defects, but it is very slight (2-3% higher risk than non-cousins, which makes it almost non-existent.) The idea that you shouldn't marry your cousin appears to be mostly confined to the United States, and only in modern times. Like circumcision, it's just another weird American sex-related taboo, with no basis in reality.

Yes and it is gross.  There are thousands of people in the world.  You need to meet more people and quit hanging out with family so much.  Your children will come out mentally retarded.  What is wrong with you?  Has your parents not taught you any morals.

Pitbull,    Not all the offspring of first cousin matings  "will come out mentally retarded" to use your words.   Also there is family physical disease too.    Though the risk of genetic disease ie Cystic Fibrosis is higher in first cousin offspring ,many offspring are normal.  I was taught that the chances of genetic disease among such children is 8 times higher than in unrelated parents. This is because first cousins share 1/8 of their genes in common.
I wonder do you think it gross to mate parent and child and brother and sister ,(both sharing 50 per cent of their genes ) as breeders do to create pedigree animals!. Just interested in how you feel about that practice. Cheers.

Yes it is! Maybe in another place it isn't but united states yes

It depends on where you live. In some places , it is illegal.

well that's your relative.

You need to check your state laws as it varies from state to state.  Even if legal, not a good idea because of possible birth defects, lower intelligence, etc.

Just wanting to know if it is legal in texas to marry your first cousin, and I am the 2nd cousin.

It is legal in about 18 states to marry a first cousin. Six states allow it under special circumstances.

As far as birth defects, the rate among cousins is only 2-3% higher than non-cousins.

And while people may freak out about the idea, marriage among first cousins was very common in this country from colonial times into the 20th century.

As far as I know its not illegal to marry your 1st cousin.  However, it should be.  I mean that's a little too close to home.  Cousins are almost like brothers and sisters.

No, even in some cultures it`s legal, I`m not saying that it`s legal in anywhere , but it`s legal in many places of the world but if you don`t want, you can be without marry because it`s not bad neither

It is only illegal to mary first cousin in only 20 of the states of the United states. Check it out.  Royalty practice it explicitly to keep their gene pool pure and the assets in the family.  Get informed.
