It’s so much more than that. It’s a heart connection. That’s why having sex outside of marriage (or committed long term relationship) can be so damaging.
Asking how can one know if they’re compatible if they don’t try before marriage is a pointless question.
Because you can know before you ever engage in sexual intercourse.
I waited. But we both knew we were compatible because we didn’t abstain from touching each other and talking about what we liked.
You see the way I see it is this: if you know your own body you can actually make yourself compatible with your partner. You just need to communicate your needs, and they theirs. You have to be on the same page, emotionally and mentally. The physical side of things will follow.
I don’t pretend to be an expert about these things, but I think I’ve managed to prove a couple of people wrong on that front.
Waiting until after marriage has actually made it all the better.
One more thing. In the end, it comes down to the act of love.
God, who is Love incarnate, created the act of sex to be enjoyed between a married couple. It is the ultimate show of love and trust in a relationship.
For me, waiting until after marriage was the best decision I ever made.
