“most people getting married today are not virgins. With people having sex at a younger age and choosing to get married later in life, most have already had many sexual partners and lots of experience before getting married.

No surprise then that for a vast majority of us, monogamy does not come easily after years of sexual freedom and seems to be an almost unrealistic requirement of wedlock.

And yet we trot to the altar with blinders on, as if we’re living in the Victorian era when chastity and monogamy were paramount, and adhere to the same defining principles of wedlock today.”
