The guy might just be a dumb misogynist too, as in men are the only gender that can think rationally and all women are just hysterical little girls who don't know what they really want and are ruled by hormones like cats in heat.
I'm going to be 34 this year and I never felt any urge to reproduce after hitting 30, or at any age for that matter. I didn't feel any biological clock kick in, I've never wondered "what if" or if I'd have a boy or a girl or any of that shit. I see many friends breeding on purpose and I just wonder what the fuck's wrong with them. The funny thing is I've been told by more than one person I display maternal behaviors sometimes... just not toward kids.
I think that whole biological clock horse shit is a mix of "gotta use those eggs before they spoil," the increase in sex drive many women experience in their thirties and societal/peer pressure. So they feel the need to take their shot while the target's still in range, but often not out of any genuine desire to have kids. Meanwhile, men can father kids in their senior years - maybe not
healthy ones, but guys can become fathers in their sixties. You never hear anyone giving a guy crap about his biological clock ticking away.
But from a biological standpoint, it's not different for women. Women just get a lot more shit about not breeding. If a man dies unchilded, people will say what a smart guy he was, never tying himself down with kids and will go, "Wow, look at all the things he did in his life!" all because he had no brats. If a woman dies unchilded, everyone will pity her because she never became a mommy. Even if she accomplished equally great things personally, creatively, professionally and so on, she'll be reduced to her reproductive tally because apparently women are nothing if they aren't mommies.
Biology is not destiny - we ignore and violate nature's course on a daily basis when we do something as simple as take an aspirin for a headache to something as drastic as getting treatment for cancer or getting an organ transplant. So why is reproduction the one part of our biology we're supposed to succumb to?
Thankfully, I don't get too many bingoes, partly because I keep my CFness mostly to myself and partly because I think people know what a weirdo I am and figure I'd be a bad parent (I know I would be), so they don't encourage me.
