I've had people say that I got married too young as a man aged 26. Essentially, the logic goes that you're too young to get married until you're almost 30, but you'll probably not be able to restrain from having sex from age 16 to 30, so society will bless your string of sexual partners until you settle on one. And you better not settle until you have a degree, career, own a house, car, etc.
There are those women who follow a man around the country while he gets his advanced degree only to see him marry someone else when he graduates.
