I spend a lot of time being light and salacious here. But I've got the mind of a scientist (its genetic, dad's a physicist) and I find that I'm always looking at scientific reporting from the point of view of cuck/hotwife/swinger who knows that some fair amount of our alternative behavior can be explained biologically, psychologically or sociologically. Some folks look at you like your a nut job when you start expounding pet theories behind the enjoyment of wife-sharing etc. Some folks just aren't that interested in the anthropology of their own craniums. We'll, that ain't me, babe.
There's an article in Slate I just read that explains pretty well why men have ridges on their cocks. And it explains why sloppy seconds are sloppy. It has to do with the propensity of women to cheat, and why biologically it makes sense for them to do so. I won't go through this whole theory blow by blow but basically boys are shaped the way they are so they can scoop out their rivals goo and plant their own. And when they say size matters, it may, in so much as it allows for a deeper delivery of man sauce. When your wife comes back from that next work trip, you know you will want to fuck the hell out of her. VSK and I always joked about it as "reclaiming my territory." Turns out we were right according to the theoretical biologists.
All this matters not in the realm of justification, because I don't really hew to what is right and proper in all matters matrimonial. On this day in celebration of romantic love I'd like nothing better than a three-way. But given that its Survivor night and the VSK is a fan, I'll settle for her happiness and a late night rogering. She'll get this valentine and maybe a surprise or two. Our biological wiring, and keeping an open mind to it, provides quite a few surprises to the couple that listens carefully.
