It is often said within Christian circles that sex is better and more enjoyable when kept within marriage. There is unquestionably a Biblical argument that marriage was designed by God to be enjoyed by committed, lifelong married partners. But secular research on sexual satisfaction shows the exact same thing: sex is almost always more rewarding and pleasurable when shared with a single married partner.

Why is this? Creating an exclusive sexual relationship increases your investment in your partner, which increases your incentive to develop your emotional and sexual intimacy, which naturally increases your ability to bring each other pleasure. The longer you stay with a single married partner the better you will become at sharing sex that is enjoyable for both of you. Sex within marriage is also viewed as sacred and can be enjoyed without guilt. Investing more in the sexuality of your marriage will always lead to better sex as you continue to grow alongside your partner.
