Quite normal- especially if you were raised in a traditional 2 parent family and around other stable relationships, where a marriage was considered a vital part of their life. So it gets to be ingrained in us as kids to do what we see around us. In today's western world we do see fewer people getting married at an earlier age, if at all, and much fewer long term relationships. But I think that is primarily because the sexual revolution of the 60s and 70s is now the norm, and sex outside of marriage is no longer looked down on. When I was growing up in the 70s it was assumed everyone would get out of high school, get a job or go to college, and of course get married soon. Just the way it was done. Those who did not get married by 25 were looked at as being maybe gay or otherwise strange. Today the average age to marry is way older than 20. But yeah, you are normal, it is normal to want to have a wife and have kids if you grew up around kids and enjoy them. I know some younger people today who grew up without many other kids in the family, and they frankly don't have any interest in kids. See them as a pain to deal with. That may be the millennial attitude of focusing on oneself and not others.
