Anyone with the slightest knowledge of the Abrahamic tradition knows that sex was not the "original sin". This is not a revelation. I find your ideas on sex a bit disturbing. Not because they are too liberal, but because they are still arbitrarily restrictive. It seems as though you are trying to establish a sexual morality in which you get to have multiple partners while claiming that it is not your desire, but rather God's desire that you do so. Yet ultimately you're just pushing Djj's sexual preferences and claiming they are God's. Case in point: You've declared that anal sex is bad. What was it you said? Something about it harming the body and the soul, yes? If you'd said "It's just not my thing, but if other consenting adults want to do it that's fine as long as they conduct themselves responsibly, as they should in any sexual encounter" then I could agree with that. But the fact that your finding it icky leads you to declare it unnatural and dangerous helps to convince me that you are just trying to elevate your own sexual preferences by declaring them superior to those of others.
Here are my personal sexual rules:
1. Everyone involved is an adult. Non-negotiable.
2. Everyone involved is consenting. Non-negotiable.
3. Everyone involved should act responsibly to avoid unwanted pregnancies or the communication of diseases.
4. Everyone involved should be honest about what they want (or don't want). In other words don't be deceptive to get what you want.
Why should we accept you as an authority on human sexuality when your prophecies are false and the math you use to "prove" those prophecies doesn't add up?
