Nope. No kids. But I've known my whole life that I wouldn't have any; same with my wife. I'm afraid I'm constitutionally unfit for having children...just my own shit...I'm very happy for folks who have a loving family.
For me the best (non-carnal) thing about getting the vasectomy was that it took the whole issue of kids off the table. Neither my wife nor I wanted to start a family. But we were getting pressure from our parents and some friends to do it anyway. We even second-guessed ourselves from time to time, wondering "what's wrong with us? Maybe we're being selfish by not procreating." When I finally made the leap, that all went away.
