Dear friend,
I am an orthodox Jew, you do not know the teachings of the prophets. The prophets taught that you must be HOLY, not just stay clear from physical activities that get someone in trouble in the public eye. For HaShem, the God of Israel sees all thoughts and imaginations as a billboard sign on the side of some highway, or as the full moon on a cloudless night.
The commandment: "You must not covet" deals with the heart. HaShem is telling us to keep our hearts pure in the commandment. What you "desire" is to see nudity prior to marriage, thus your intentions are purely evil and vile. Your motives are corrupt, your fantasies are corrupt.
Furthermore, the Catholic church took our bible, the Jewish bible and they teach things that our bible does NOT teach. The Torah or the law of Moses does teach that masturbate is allowed, but your thoughts must not be upon women that are not your wife and especially not men and especially not animals. Thus, if you can arouse yourself without delving into women or the physical body of anything, but just yourself- enjoying yourself fine, but if you do not think you can - stay clear from such - for you will sin.
The thing about so-called "Christianity" is that it only teaches about 5% of what our book says. Without knowing the rest one comes out with questions such as yours. I am not being rude here, just sincere. Look, I have a weekly radio program in Fort Smith, Arkansas and I delve into these things all the time.
Let me give you some commandments in the law of heaven found in Deuteronomy and Leviticus, Okay:
This one deals with night visions:
If there be among you any man, that is not clean by reason of uncleanness that chanceth him by night, then shall he go abroad out of the camp, he shall not come within the camp: But it shall be, when evening cometh on, he shall wash [himself] with water: and when the sun is down, he shall come into the camp [again] -Deut 23:10-11
This deals with intercourse with one's wife:
The woman also with whom man shall lie [with] seed of copulation, they shall [both] bathe [themselves] in water, and be unclean until the even - Lev 15:18
This deals with masturbation, because when a wife is unclean in other areas a man must not be with his wife during those times, so here is the law:
And if any man's seed of copulation go out from him, then he shall wash all his flesh in water, and be unclean until the even. And every garment, and every skin, whereon is the seed of copulation, shall be washed with water, and be unclean until the even - Lev 15:16-17
Thus, virtual porn is evil, because your thoughts are fornicative and even adulterous if the fantasy is based on you approaching a married woman, for you think to yourself, I would like to be with that beautiful married woman; or.......
Those thoughts are vile in HaShem's sight, for this tells Him you have no integrity. Just posing this question tells Him you are evil, so please repent.
and turn from the Catholic Church
