WOW! that is a lot of drivel. not just in the article but the comments too.
I am/was a cheater, so no holds barred there. my wife and i survived, but lets face it, Monogomy is an atiquated notion. Polyamory, Swinging, Open relationships, that is the future. We went through a long period of discovery and adjustment, and believe that if more couples had open or swinging relationships there would be a lot less divorce.
Separate sex from intimacy, the act from love, and you will have a much richer, open and truly loving union.
Then WTF is sex then? Just a physical act? Connect yourself to a masturbation machine. You are just feeding your addictions, that is all. Yeah we can all adjust and learn to be addicted. But what is the fucking point? Hey raise your hand if you can be an addict too.
Like any addiction, you'll need to ramp up the thrill, so you can't be too far from fucking dogs in the ass and having a horse fuck your wife and rip her vagina to shreds.
Edit: apparently you two are not doing the sexual acts to create pregnancies. So this isn't sex as an R strategy (see @skeptic).
