I thought that’s probably what you meant. I have no problem at all with discussing such subjects, here or anywhere else. In fact — since the difference between salvation and damnation, for so many people, hinges on their relation to sins of the flesh (and desiring sexual compatibility within marriage absolutely is no sin) — this part of life needs to be discussed, and discussed frankly. Many people have an issue with doing this.
One thing I’ve found in this 45±year journey throughout the Catholic world, is that on one level, the Catholic Faith presupposes ideal behavior. What I mean by this, is that when sin is committed, even if it is repented of, there are sometimes things that just can’t be undone. Let’s say, for instance, that someone is divorced. The estranged spouse is remarried. Reconciliation is impossible. That person seeks to become a Catholic. Their marriage is reviewed for possible invalidity. Bear in mind that non-Catholics are not bound by canonical form, and their marriages are presumed valid unless proven otherwise. The tribunal comes back and says we’re very sorry, but your marriage was valid, we can’t find sufficient proof of invalidity. You cannot remarry in the Church as long as your spouse is alive. You may become a Catholic, that’s fine, in fact, you should, but you are still married to your estranged spouse. The cost of discipleship isn’t always distributed evenly, and according to our human lights, it just doesn’t seem fair. We can only tell this unfortunate person that their reward in heaven will be greater, because their cross is heavier.
And so it is with bringing illicit sexual experience into a marriage. I do not mean this in any lewd sense, but there will always be the tendency to compare past lovers with one’s partner. What happens if sex with one’s spouse isn’t as gratifying as with one’s past lover or lovers? What if, compared with those lovers, your spouse “fails the test” entirely? How do you get past that? I don’t know. Some might say “love hides all faults”? Yes, but what if it doesn’t? I’d be a poor one to ask. I was a male virgin when I married.
