As someone mentioned, there's no blueprint to life. I nearly got married when I was in my mid 20's and looking back, it would have been a horrific mistake. Which would have been compounded if we had had kids.
My own advice, without knowing specifics. Get settled in a career, start banking some money. (Money trouble causes issues) Enjoy being together and travel. Get engaged when it feels right, not because of pressure. There's a fine line to things, but getting married early isn't for everyone. I'm 37 and for every couple I know that got married young and has made it, I know two couples who did the same and are divorced. Don't rush it.
And finally, marriage can be wonderful and kids are amazing. But here's the simple truth. Once you get married, the topic of kids inevitably comes up. And once you go down that road, any spare time you thought you had, is gone. So travel, go to the SEC tournament, do that stuff now, together, because it will change some day.
