I had my first at 32, hence the “still in college” post :)
LOL!
Big discrepancy between us early boomers born right after world War II and those born in the 60s when we were “coming of age.” I got married at 22 and was the oldest of “my group” to get married. Combination of what our mother’s had done, and the pressure of most of the young men being in the military during VietNam. Lots of marriages before the guys left or immediately upon their return. My husband was 25 and a Vet and was the oldest of his friends to get married too! LOL On the other hand, none of my kids married before 30!
