Maybe it's the WAY they're made they want rather than kids themselves. Lol
That stork is a very special bird everyone wants to see! HahahahaI wanted kids because I love kids. I had 4, now I'm waiting for grandkids.
Depends on there experience, It may be because they did not have any brothers or sisters when they where young.
"don't give me any of that "primal" bull"
Answers as to the proximate reason why men want kids so badly not underpinned by the ultimate reasons ( ignorantly called " primal bull" ) are BS answers.
