Keep it in the Family??

So I was having an interesting convo with an international friend whom I'll refer to as "Jorge"...

Jorge: yeah, I'd get drunk and dance all the time.
Jorge: this one girl I knew would make fun of me and call me a "ballerina"
Mel: :bakla:
Jorge: but that's okay cuz I eventually banged her.
Mel: :rofl:
Mel: the last time I did crazy drunken dancing was at my cousin's wedding
Mel: hell, that night I discovered I could breakdance
Mel: but anyways, it was kinda weird...I couldn't dance with any girls cuz all the girls were my freakin' cousins.
Jorge: what's wrong with that?
Mel: :uhh:
Jorge: back home we'd dance with our family all the time.
Jorge: we'd do that thing where you put your leg between hers and she'd do the same
Jorge: and you two would...how do you say....rub?
Mel: you mean like grinding?
Jorge: yeah.
Mel: :uhh:
Mel: yeah, that's kinda frowned upon here in the states, dude.
Jorge: really?
Jorge: what about banging your cousins?
Mel: :omg:
Jorge: you can't bang your cousins??
Jorge: not even if they're hot?
Mel: dude, no!!
Mel: I mean, I'm proud to say that I have good looking cousins...but no...that's just...no...
Mel: cuz dude, the way I see it, it's like
Mel: me...my mom...her sisters...their daughters...
Jorge: no no no, it's quite simple:
Jorge: there's your penis...and her vagina.
Mel: no no no...it doesn't work that way...
Jorge: but it's the best!
Jorge: cuz it's like you two grow up together and you have a connection
Jorge: and then she's all pretty and you want to have sex
Jorge: she doesn't have to worry about getting hurt because you're family!
Mel: dude, you just said "sex" and "family" in the same sentence!

So yeah, his little persuasive speech didn't work on me.

Then strangely a couple days later, this article came out: Study: Most babies born to first-cousins are healthy.

But sorry, I'm still not convinced; my cousins are here strictly for potlucks, drinking and karaoke.
