Ok, I'm going to agree with you folks that if a couple was enjoying a traditional marriage and all of the sudden one spouse brought up this arrangement, it would most likely be a good reason to hit the marital panic button. Totally understandable!
Speaking for myself, with the right man, this is something I would bring up early on in the relationship just to see where he stands on the subject. And if I really, really liked him, I wouldn't necessarily dump him if he vehemently objected.
But again, the odds of me finding someone:
A) compatible with me
B) willing to put up with my numerous and varied idiosyncrasies
C) as in to bad 70's **** as I am
D) who can sing a Johnny Horton tune in its entirety
E) who loves to smooch on a cold, rainy day
F) I'm still thinking about smooching
G) who has never killed, wanted to kill, pretended to kill or plotted to kill a polar bear
H) who thinks my tractor's sexy
I) who would humor me and let me serve lefse at Thanksgiving dinner...and eat it!
J) who wouldn't interrupt me when I'm watching "Family Guy" or "Ghost Adventures"
K) who would love me even when my Vikings beat his team out in the play-offs
L) who would take out the garbage
M) who would let me sleep on the right side of the bed
N) who thinks plaid Vikings pajama pants are cute, as well as nerdy glasses
O) that isn't a serial killer
P) who knows my favorite color, flower, holiday, seaon and my eye color
Q) who won't yell at me if I get in a fender bender after buying a new pair of shoes
R) who will take me on a corn field maze date extraordinaire!
S) who is as good at cuddling nude in a sleeping bag with me as emkay is
T) who not only understands my love for black Sharpies, but nurtures that love as well
U) who doesn't think I'm a complete geek for watching Adult Swim
V) who would teach me how to shoot a gun
W) who would make mercury stop picking on me!!!!
X) that actually read through this entire list
Y) Where was I going with this?
Z) Oh yeah....who would be open to a "don't ask, don't tell" week vacation.
Are slim to none.
