When I was a child in the 50's, the church was paranoid about heterosexual sex. Females were looked upon as a source of temptation for priests (and all males for that matter), and the church bent over backwards to avoid any male-female scandal amongst its clergy. And guess what? That attitude may have spawned a certain tolerance of homosexual activities among priests that eventually carried down to activities with and the molestation of young boys in the age range when they were just reaching puberty and were naturally curious about their bodies and the changes they were undergoing. I feel that a healthy dialog about sexuality within the church at that time (which of course would have been very unlikely given the times and its paranoia) would have avoided many of the problems we see today.
Nah. Sexuality is best when kept private (I'm talking about the consensual type, not abuse). From what my Dad tells me, there were more straight priests in his day (he was born in 1946) and that, with the exodus of priests beginning in the '60s, the Homos started coming in big time.
Having "open discussions" about sexuality has not helped the LARGER culture one bit, as seen by the increase in pornography, divorce, etc.
