So, this observation leads me to wonder whether sex that cannot produce children, because it is masturbation, or because of contraception, or because it is homosexual in nature, is or is not a moral issue. Who cares, other than those engaged and pleasured, and why should they? By what right do they think they have any involvement, at all?
eg:
On what rational basis is this assertion made? How does Catholicism come to think itself privy to God's purposes for sex, and what is its justification for this presumption?The Catechism of the Catholic Church (CCC) teaches that the sexual function is meant by God to be enjoyed in "the total meaning of mutual self-giving" (CCC, n. 2352) within the marital relationship of a man and a woman.
