Aw, that's cute. Congrats! <3
I know a lot of people will say that you are young and all, but there is no right age for this. Besides, even if it doesn't turn out to be like you imagined, it's still a worthy experience that will add some things to your knowledge/XP.
I'll just give you one advice: marriage requires good will from both parts to prevail. With time, things tend to get boring/repetitive, so it's up to the couple to come up with solutions to shake that up... such as trips, sexual fetishes, etc. Just be creative and don't let it cool down!
And good luck, I'm sure you both will be happy!
EDIT: Oh, I forgot to say: Don't be so quick with the whole parenthood thing. It's an important part of life and I'm sure you'll enjoy it, but things are never the same once kids come into the scene. So take some years off to enjoy your marriage before becoming parents. 
Bet with Teeqoz for 2 weeks of avatar and sig control that Super Mario Odyssey would ship more than 7m on its first 2 months. The game shipped 9.07m, so I won
