"There was only one time in my life I felt as you describe though, the first time I got pregnant. It seemed miraculous to me that my body could create life. The feeling of walking on air lasted about a week, and then the knowledge of it absorbed into my being just like everything else. I was still happy, but it was calmer."

This and breast-feeding are the two things that I specifically envied my wife about with our children. I have been a loving, nurturing parent and have a very good relationship with my (grown) children as I had with them as they were growing up. But I didn't carry them in that unique fashion that belongs to most GGs nor did I breast-feed them (literally feeding them from my own body). I guess that the latter is possible for men, but fairly improbable.
