i can echo.... 'we do exist'... and some of us get old 'not finding'... :(
No, it's not unrealistic. To me it isn't for biological reasons that i will want to have a child, it's the things i can teach them and help them grow as human beings. Honestly I would like to pass on my genes, but it's not really...it's just something i want to do. It's not a huge deal for me because it isn't really useful, raising a biological child would be no different than raising an adopted one and teaching them the same as you would teach the biological one.
I'm guessing the animal instinct inside of me, but what i really want to do is pass on my mental traits.
That's what the original poster is looking for, yes.
More than that, though, I've gotten the impression that she wanted to know why so many guys want kids. She ended her post with a series of questions. I certainly don't think she intended this to be an exclusionary discussion in which only those who don't want kids are allowed to participate.
I like kids just fine but have enough fun playing with relatives children . I don't think it's unrealistic as long as you are up front about your expectations going into the relationship.
