As others have pointed out this is more about the person you marry than the act of marriage. But realistically if they like to cuddle on the sofa and watch 10 episodes of Ugly Betty with you and you want to code, you'll probably work that out a long time before you go as far getting married.

What does make a massive difference is kids. And more precisely sleep deprivation, especially in the early stages. Coding until 2am, going to bed and 5 minutes later a little person is crying and you are up again etc is hard. Also when you are just a couple your SO might not mind you rolling out of bed at 10am, but most aren't going to be too happy about having to get up at 7am 7 mornings a week to look after the kids whilst you are snoring quietly. And even if you do get away with that, don't discount the amount of noise etc that at least stops you from getting a great sleep. Some people get lucky, some people think they "trained" their kids, but for most people the first few years are tired years.

And as they get older your unsociable hours don't really work either. Most kids operate from around 7 to 7/8. They wake up in the morning they want to jump on your bed. They want you to tuck them in. You'll love it too - but family life is hard to balance with the typical lifestyle the average hacker on here probably lives.

Please note it is not all bad, I work from home in an office in my garden and see my kids for hours every day - something most people don't get. You probably also have more flexibility to go to sports days, plays etc. But never underestimate the tiredness in those first few years!
