I think you're being very, very arrogant by believing you know how everyone's relationship will progress. My wife and I were sexually active before we were married, yet we're happy and bonded.
People on one side of this debate seem to think they know the answers to everyone's life, and it's getting extremely annoying.
If sharing experience and insight makes people "arrogant," I guess all communication is inherently offensive.
On the other hand, I might be the most pathetic, shopworn, slip-slidin', substandard, ditzy person in the forum --- now there's a topic for a panel discussion! -- but the truth is still true, and saying so is not arrogance.
As for your personal relationship, I know nothing about it and I have never commented on it. If you are happy and bonded with your wife, I rejoice with you. You have a precious gift of love. May you and your missus have many, many blessings!
