Stop immediately. This is genetically dangerous to you, your cousin and any potential offspring.
Incest is death and disease, it violates natural law and will destroy you.
Do not engage in this, it is very, very detrimental and destructive.
If you are trying to be forced into this in a restrictive nation where your rights are limited, you need to reach out to Father Zeus and your Guardian Daemon for help, as this situation would be greatly harming you and your cousin. Also see what you can do legally to escape a situation like this where you are being arranged for this against your will if that is what is occurring.
People need to study history, and perhaps their own family tree...
Second cousin marriage was very common all through history. It's not ideal, but it's not really bad like first cousin or sibling which the above replies are making it out to be. It is genetically far apart enough to not be incest.
For those of you who do not know, you can search "cousin calculator" online and you'll see the chart explaining the links. It's not a very close relation, you have ONE great-grandparent in common, that's it.
