I find it hilarious that those who take an oath to refrain from sex issue decrees of regulations, i.e. climaxing from male on female oral sex is Ok but somehow the sperm is sacred and only should be “naturally” ejaculated into the vagina thus climaxing from female on male is a “sin”. Some artificial contraceptives should be avoided (Those that do not prevent conception i.e. the “pill”) but those who say your soul is in peril if spontaneous sex between a married couple who happen to use a condom for instance is ARROGANCE. Where is this condemned by God not from “traditions” of men who take a vow of chastity?
God's Words, mutual agreement and a Spirit filled conscious, that is all when it comes to the marriage bedroom.
I’ve never been told that sperm is sacred by a priest but OK. I don’t think anyone’s soul is in danger just because they use contraception either. It’s your personal life though so I’m not really going to comment further.
I’m not sure the information you’re getting about RC teaching on what’s okay is, uh, okay. Can you cite some sources?
