Good article and a great highlight of just how crazy brain chemicals end up making a lot of our decisions for us. I'd just add, don't even think of getting married for the sex - that all changes.
Actually I don't think the quantity of sex actually changes after getting married. I think people think "Well we spend about 10 hours a week together, and we have sex like 3 times... that should mean in a 168 hour week I'll have sex like 50 times!" No, you'll still only have sex 3 times in a week.
My wife and I used to live in separate countries (before we were married) so when we saw each other we managed to get about 4 months worth of sex into 2 weeks. I get just as much sex now that am married as I did before I was married, just now I don't have to go through 4 months of celibacy in between it.
Honestly the sex doesn't change, if anything I get more now that I'm married, and I certainly get it more regularly.
My personal advice: never expect to get more sex by getting married. If you get it n times a week, evaluate if that amount is enough for the next 30 years, if it's not slap yourself in the face because if you fuck it up you could well get 0 times a week for the next 30 years. C'mon we're geeks, our chances for sex aren't astronomically high.
