I got married at 18. We had a small morning wedding with just our close families and had a nice lunch afterwards with cake at a local restaurant for our reception. It was simple and lovely. We didn't have our first child till I was 22. My family never pressured us into having children, although we did start trying when I was 19 but it took a while. My parents also got married young so I'm not sure if that made a difference or not. I think it really depends on the people involved not the situation.
One question to those who got married earlier...
did you get a lot of pressure from family and others to start having kids? That's what I'd be afraid of and hence why I'm not in a rush to be married right now. I love the romanticness of marriage and what it represents, but to me a wedding is basically like putting on a show... I'd rather elope or have a simple, small one. I don't know if i'd like the expectations that come with marriage at such a young age. Am I just over-analyzing this?
