I think about this a fair amount. I have friends my age getting married (best man in my best friend's wedding in June), and then some older friends who are now going through marriage difficulties.
I DO want to have kids. At least 2, but hopefully 3 or 4. I'm all about "spreadin this seed", and want to find someone worthy of sharing my genes with.
However, I am struggling with the idea and institution of marriage. Especially here in California, where so much of the hard work I've done can get ripped away SO easily.
At this point, I don't think I want to enter the institution. And if I do, it'll be after I'm already very comfortably wealthy, and I'm getting an iron-clad pre-nup. You enter with nothing, you leave with nothing. And if I marry an ambitious woman who strikes it rich, I deserve the same.
Sidenote: If you're ever in loud alpha male drinking party mode, go to the bar and scream shit like "WHO WANTS TO GET A PRENUP!!!" and stuff. You will get fun responses.
