What a delightful family reunion!

(Wouldn’t concern me in the least – first cousin marriages in my family tree.)

No. Just an incredible coincidence to meet two sisters named the same as my biological sisters that I never met.

Bea and Kay were pulled from [thin air](http://www.youtube.com/watch?v=rHTHo6vsWVY) to preserve the identities of the innocent.  
I assumed the Allan Sherman fans would pick up on it…

I didn’t think of the dick angle. I thought it may have referred to having experienced a **B K** “sandwich”.

Yes, because crazy hypotheticals are an exact mirror image of real life.

listen folks - you can wait 5 minutes to check/answer that text message - even if it is, in fact, life or death - those 5 minutes are unlikely to make any difference in the end.

same rule applies when your driving.

Yes, but spermatozoa cannot “survive” the low pH of gastric acid.

It may be time for another poll: “Had you ever used the word ‘coitus’ before ‘The Big Bang Theory’ hit the airwaves?”

Me: No.

No problem with the consenting-cousin question here, either. Thanksgiving might be a little awkward, is all.

My cousin? Stop immediately, run do not walk to the doctor and get tested for all known venereal diseases and parasites.

(This has nothing to do with her being my cousin, and everything to do with the kind of person she is. Eew!)

I’m only grossed out by sex with my actual, known cousins when I’ve known since childhood. I’d totally date someone who happened to be an unknown bio spawn of one of my aunts. What’s the big deal? It’s not like all my boyfriends haven’t been just as crazy as my family, anyway.

You have so many incredible stories **ducati.** What I like best about them is how not made up they seem.

There was no poll option for “Ask cousin how they want to proceed” which is my answer - I mean, I’m cool with cousin-boffing, don’t see the slightest thing wrong with it, but informed consent and all that…  
…hell, it might even be a turn-on for her! It would be for one of my RL cousins.

ETA; Or so I’ve heard…

Maybe a better version of the hypo would be replacing the incoming texts with, “Hey, why do you have a picture of my grandparents on your dresser?”

Well, no, THAT I would stop for, and preferrably before then to call 911 and administer first aid (and put pants on before the EMS arrives). I mean, gotta take care of family first, right :D?

> 1. [Map of where cousin marriage](http://en.wikipedia.org/wiki/Cousin_marriage_law_in_the_United_States_by_state) is legal. As long as you’re on your phone, look it up.

Legality wouldn’t enter into it. I would recognize my one female first cousin. Any secret cousin, aunt, or uncle would be born out of wedlock, and would not legally be my first cousin. The same basic thing goes for second cousins and first cousins once removed. So we’re dealing with a cousin that is at least three degrees out, and I am unaware of any place where that’s illegal.

That said, even if it were possible, the scenario makes it clear that we didn’t grow up together, so it would not be squicky to me. Though I am surprised that most everyone else is okay with it. It makes me wonder why such is used as a negative stereotype about hillbillies, with jokes about us going to family reunions to pick up dating partners.
