You have no knowledge of history. The secular stigma on masturbation didn't begin until the 19th century with the quacks of the medical profession in the Victorian age. The only stigma which occurred before then was from the Roman Imperial Church of Constantine. This was a by-product of Manichaeism being incorporated into that religion.Used to be neither was approved.
So, a women who has had the uterus removed for something like prolapse cannot have sex with her husband anymore since it is no longer sex - it, according to you, is masturbation. Husband and wife can no longer have sex. Right, that's the Roman Imperial Church for you. Infertile women have to become nuns. Any form of birth control is masturbation.Sex is combining a man's DNA and a woman's DNA to attempt to produce offspring.
Not-a-St. Karol Józef Wojtyła didn't ever seem to have a problem with Priests and homosexuality even with young boys. He only started to do something at the end of his reign.Pope St. John Paul's Catechism calls homosexuality "disordered", or the desire for homosexuality.
Clearly, you do not understand what Jesus was teaching. Adultery in Greek is a very specific word meaning a man having sex with a married or betrothed woman. This is not just any sex. Jesus also made it clear that he was not rewriting or changing the law. So, if one looks at the tenth commandment - Don't covet. - one can better understand that Jesus was reiterating the tenth commandment - not changing the law.And to make light of this is to call into question just how well you understand Christ's teachings on how lust is equal to adultery, in seriousness, or in gravity.
