My wife and I had a very smooth transition to married life. We had put down a bunch of things in a notebook, ranging from big stuff, like our beliefs on finances and our bucket lists, to little things, like where to spend the holidays and our idiosyncrasies. Because of that, we knew a bunch about each other and weren't really surprised by much.
We just finished our second year and it was, in many ways, better than the first. Here are some things to look forward to:
1. The sex will get even better. I saw in another post that your drives are mismatched. It was similar for my wife and I at first, but as she grew more comfortable with her body and in my desire for her, her enjoyment increased and her drive with it. You may also find your drive increasing as your love for your husband grows. And, of course, the more you practice anything, the better you get at it.
2. Life should start to relax a little bit around you. If you aren't ready for a house or family, then enjoy a year that shouldn't have such life-altering changes. Use this time before kids to really grow both your relationship with God and with each other.
3. You'll have fewer issues and disagreements. By now, you've probably come to compromises you can both live with on a variety of issues. I would suggest having a very open and honest conversation to ask if either of you are unhappy with the current arrangements, but assuming you are both satisfied, then you should know by now everything from what the other considers a waste of money to how they like their coffee. You should become more of a well-oiled machine, which should take away some of the stress of marriage.
4. Now for the (potentially) bad news: you'll realize that some of your husband's imperfections are here to stay and he'll realize the same about you. How you each react to that will go a long way toward determining your happiness in the second year. But with an endless supply of grace and God, this year can be ten times better than the first one.
