It can take a year or more to really get to know someone, and 35 is considered a geriatric pregnancy. It doesn't matter if you're a 50 year old guy. Don't let bitter & lonely women convince you that there is anything even slightly wrong with looking for someone in their late 20s or early 30s if you want kids & a family.

What about love? Just curiosity...imagine you fall in love with a woman who is older and does not want to have kids, will you give up on love, to have kids and a family?
I am not pursuing love or a relationship with anyone who cannot potentially be a mother to future children, so I don't see it as a big issue. If it turned out that the person I wanted to have kids with couldn't have them, that would be a very unfortunate thing, but I'm sure we would investigate other options.
But I would ideally like to find someone who is healthy & intelligent & attractive so that we might pass those things on to our kids.
One would hope that an adult that knows they want children, would have that conversation with their potential mate well before falling in love.
Perhaps categorize this as healthy boundaries while dating? Defining expectations and what each adult wants out of a relationship PRIOR to allowing themselves to bond over infatuation or lust alone.
That is a good answer and I agree. Compatibility between couples is important. I just think that sometimes, you don't choose who you fall in love with...
Yeah, if the two people are younger the likelihood of this is probably higher - makes for a tough situation... But having that spector looming over the relationship (where one person wants children and the other does not) is a recipe for disaster... Unless the person wanting children can truly be at peace letting go of having children.
Tough all around. Having true love is it's own blessing though, so I'd hope it could work.
I had a couple of friends, they were married for 11y, but eventually they did separate. He wanted kids, she didn't.
They met when they where like between 22/25.
He, soon after got divorced to her, married to another woman and had kids....3...
I met her one day and she was desolated....and seemed a bit regretful. Life is made of choices.
Everyone should pursue their dreams but I think is wise to have flexibility and have an open mind.
We never know what challenges life through at us.
Only a woman would ask such a question
While I agree that anyone can choose who to start a family with, regardless of age *on either side*, I don’t know who considers 35 a geriatric pregnancy 😂 If it is the medical establishment, well then I trust that designation even less.
I know countless women who had kids after 35, and they are amazing moms and in healthy relationships.
Often the older moms are actually better moms in many ways, being more mature, more secure in themselves, more experienced in life and in relationship.
The bigger age gap you suggest also can becomes a huge issue later on when the women is just 45 and her husband is 70, or she is 55, still young, and he is 80.
All that aside, if a guy gets to 50 without a wife or kids, perhaps he needs to ask himself why? And once he becomes the person a woman wants to marry, perhaps think twice about purposely trying to put a young woman in a situation where she has a *true* geriatric as a husband when she is in the prime of her life, her 50s!
Something like 90% of a woman's eggs are gone by 30. Women can absolutely have children after 35 & even after 40, but if you want multiple kids, starting after 35 is definitely not ideal. Aiming to find someone in their late 20s or early 30s is a smarter approach, IMO.
None of that means it's too late for a woman in her middle to late 30s, or that they won't be good mothers or anything like that.
If you want multiple kids, starting at 50 or older for a man makes less sense than a woman starting at 35 for multiple reasons.. not the least being that sperm quality/quantity decreases 
If he can't get her pregnant then the problem solves itself. Men who are healthy and take care of themselves have fathered children despite their old age with no issues.
