Sounds like tough training for a tough job. Just because something is difficult, doesn't mean one can't do it.
But just because someone can force themselves unnaturally to do something doesn't mean that they should do it. Celibacy is wonderful for those who have the gift but not so great for those who don't. Paul said that if one cannot handle celibacy they should get married. Perhaps it might be wise to listen to what the Bible says instead of trying to make excuses for rules made up by men.Clergy celibacy is unbiblical and was unknown in the early church.
