None. Zero. That is disgusting, to date your cousin. Yes, in some states, including Colorado, you can marry your cousin, but it is wrong to date your cousin. Do you even think of marrying your cousin? No. Hell no.

I don't even understand what kind of question it is, like why is that even a question though? That's disgusting. It's weird, you know? In some culture... Nevermind. This is disgusting to ask, to even ask a question like that.
