If you're not married, or hang out with singles, or have kids who think about sex, read this post by Al Mohler.
A number of friends of mine lost their virginity in 8th grade; and other guys I know continue to run around. All these guys have yet to marry. Maybe I'm the one being sanctimonious, but I've always made a connection between promisuity (yes, I think premarital sex is a moral issue) and resistance to marriage.
Your thoughts?
