According to a sociology professor at the University of Texas, people should consider getting married when young even if all the details aren’t worked out.
Mark Regnerus has contributed to scholarly works on the sociology of sex, specifically premarital sex, in America, and he believes that the tendency of people increasingly to put off marriage until “all their ducks are in a row” is destructive to society. His reasoning is based in part on the fact that, biologically, people are especially geared for sexual activity in their late teens and early twenties, and without the institution of marriage to regulate those impulses, they engage in behavioral patterns that have a negative social impact.
Of course, for this idea to have a prayer of working, our culture needs to prepare young people, particularly boys, to take on adult responsibilities by the time they reach those years of peak sexual interest. I don’t see much of that going on except in certain segments of the homeschool movement.
