Sensitive subject: dating in the 30's

I'd like to get some opinions on what could be a very delicate subject: dating women in their 30's. As a small backstory for the unfamiliar, I got married when I was 23, divorced when I was 28. I just turned 29 a few days ago. When I initially signed on to Match and eHarmony, I was primarily looking for somebody around 23-25 under the pretense that I felt like my life was at a standstill during those years I was married, and I kind of wanted to start over with somebody who wouldn't be in any particular rush to get married and have kids. Not that I disliked being married or having kids in the near future, it's just that I wanted to be able to take the proper amount of time to know this person before remarrying so I wouldn't end up right back where I started.

Lately, I've been thinking that perhaps I wouldn't mind somebody older than I am who is a bit more mature and past all the bar hopping adventures of their early 20's. In fact, many of my matches as of late (some of whom I'm communicating with right now), have been between 31 and 35 years old. Now in a perfect world, they'd just be meaningless numbers to me. Yet I have to ask the question, if having children is a mutual goal, how long do I have to get to know the person before the doctor or somebody says "Look, if you want kids you better do it now before it's too late and the risk of birth defects and infertility skyrockets." My uninformed instincts tell me that it'd take me at least two years to get to know somebody really well so that engagement wouldn't seem "too soon", probably get married a year after that, and a child a year after that. So if I'm talking to somebody who's 35, that means she'll be 39 by the time we have kids. I know that to some people that's getting WAY ahead of myself, but isn't it a legitimate thing to think about? Are the concerns about having children after 35 all they're cracked up to be?

Any and all opinions welcome. Just please don't kill me for wondering about this stuff.

Ask yourself how many years into the marriage/relationship do you want to wait to have kids? Assume 2 yrs from metting to marriage plus the years of marriage minus 37 yrs old as the max age fro children....that gets you the afe of what to limit on the womans age based on matching.

You said you felt like you missed out on something in your 20s by being married...what exactly? The only thing would be the bar hopping.

First, you need to date the whole woman, not a womb. Really--women know only too well the ticking of their biological clocks and has been discussed here, many women are not enthused at being viewed as baby makers first and the rest of them as second.
