there's no denying that marriage provides safer sex, motif. marriage is set up to provide stability in the family...along with stability in a sex partner. most men and women do not want their wife/husband screwing others. that makes for a chaotic society. which some could argue we have right now. free love has lead america down a disastrous trail. just look at the black community. 70% of the homes have no father present. sex was there, obviously, but the women didn't want marriage. i will agree in principle that marriage destroys good sex over time. mainly because marriage takes more time and effort, more responsibilities come with marriage and thus, less time for good sex. dating sex will always be better sex, no matter how many lies people tell you. dating sex is two people trying to be at the top of their game every time. marriage sex partners know there's always a "next time".
