Kevin, in the Sermon on the Mount, Jesus said, "You have heard that it was said, 'You shall not commit adultery.' But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart." [Mt 5:27-28] What God has joined together, let not man put asunder. [Cf. Mt 19:6]” This Commandment does not only apply to married people. It applies to unmarried people and all actions, alone or with others, of the same or different sex that are contrary to chastity, decency and modesty. And yes, Kevin, you are right, contraception is not pleasing to God. The marital sexual act (union) has to be open to the possibility of fertility/conception. (That is why the male climax must occur during sexual intercourse.) 

Kevin, I have had the opportunity as part of my volunteer work of visiting older people in Nursing Homes or at Home through my Parish Church in having been taught so much by these Christian people who have become wise in their years! (continued)
