I first married at 25, and I believe that was about the right age, at the time, for me. We had good years together, but disease cut them all-too-short.
I remarried at 35, and after 21 years, looking back, I'd say the time was right for each.
So much depends on the individual, but it used to be that women matured more quickly than men. Not sure that's the case anymore, from what I see of the young folks- they seem equally flighty to me. Then again, me Sainted Mother always said, "You were born old..."
So much is lost with a divorce though. Unless the first marriage was absolutely horrible, it leaves a void that is not replaced by a second marriage. It is a bit what it must be like to be a victim of amnesia insomuch as not having a past life. But worse in that you can remember what you can not get back.
