Why is it self-evident? Up until twenty years ago, few Christian denominations prepared couples for marriage. I can tell you, as a Catholic seminarian from 1969-1976, that Catholic seminaries didn't talk about celibacy at all. Yep. As hormone-raging young adult males, we were simply left to our own devices to figure out how to deal with celibacy. Oh, we were told to pray a lot, but there was no psychological preparation, you were laughed at if you told your spiritual director that you had developed an "infatuation" with a woman. In fact, one priest told me that was a sure sign I didn't have a vocation, that I was attracted to women!
So, kosta, though things have changed dramatically, and men are much better prepared today, Catholic seminary education, prior to the 90s, was woefully inadequate in even mentioning celibacy, much less talking about how to deal with it in a candid and meaningful way.
