Cause you are dating part of your relatives. A first cousin has a considerable amount of genetic similarity to you, so there would be some degree of inbreeding if you were to have children together.
Dating isn't going to have any effects. And why would what your cousin is doing have any affect on you? It is more coincidence than anything else.

Theirs notting wrong dating your cousin because back then sisters and brothers would date or even marry

My Cousin Vinny grossed $52,929,168 in the domestic market.
It would help because you can understand that your cousin is an loser for dating the same guy you liked and she new it and that would be messed up if that he kne that the girl he is dating is your counsin but he still likes you even tho he likes your cousin
Well If you're dating your cousin I think it'll be best that nobody finds out, if you really like your cousin then keep it on the low.
Yes, it's wrong.
Yes, you can date anyone whether fourth cousin, twentieth cousin, or first cousin. Dating is going out and having a good time.
You can date anyone you want, whether third cousin or first cousin. Going beyond simply dating may raise issues with a first cousin, but not with a third cousin.
