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.
Then why is it forbidden for a male, married even, to ejaculate outside the vagina? All those little sperm have a sacred (As decreed by Holy Men of the cloth) right to implant an egg. Not natural perhaps? Why then are (Married) females allowed to climax outside of the frame of intercourse?
Questions then babble from traditions of men, which lead to even more questions.
I am not saying a man has a right to force oral sex (To climax) from his wife but why is wrong if it is mutual? Again, if it’s not natural then apply it to the female as well. Hence the sperm has some “special” little favors going for it, (I.E worthy of respect) deemed too “sacred” to “abuse”.
