unless you get a prenup! lol
I would get married, but I wouldn't just get married within the first week of knowing the woman. I'd have to wait maybe a couple years before I can decide, at which point I will think about a prenup. If I find her very trustworthy then I wouldn't need to get one. Marriage for me however is not the most important thing. I'd love to travel the world as well, by being married your outside life begins to become more suppressed, and it means you're not able to do less things (IE for me I'd be absent a lot). Of course I would also have to go and get my degrees and complete my studies before I even start to settle down. At the end of the day, I would like to do as much as I can before I get married, even if it means sleeping with a lot of girls (inb4 whore) or traveling around the world with my friends. Because I know for a fact once I'm married, I wouldn't be able to be as free as I once was.
As for having kids, my friends parents have had 2 children, (him and his sister) and they've yet to be married. They've been doing this for over 20 years. So I don't think you have to be married in order to have a strong relationship and have kids. Of course some people abuse this and have kids when they're 14 but I won't go into that.
tl;dr
I'd only get married once I think I've done everything I can in my life, and experience life at the finest I can, and also if I trust the woman which I'm marrying, and I know everything about her. However if I end up knocking up a chick I would stay with her, but it still wouldn't mean I marry her.
