Lori, you may the exception, but Christianity is responsible for perverting sex, and, I would go as far as to say, perverting human nature. Humans are naturally perfect, it is our inhereted cultural institutions that are flawed.
God has no problem with sex....people do.
Because of their incorrect assumptions about what god wants us to do.
It's just a shame when people take this glorious gift and reduce it down to the equivalent of taking a shit.
It's a shame when you consider the glory of taking a shit to be such a worthless activity. Sex is glorious, taking a shit is also glorious. Sex is something that should be done at least as often as taking a shit, probably more often. Rarity doesn't make it any more holy. When you falsely consider some things to be holy, that makes other things not. Everything is holy, which is another way of saying nothing is holy.
And for crying out loud people, you don't have to be a flippin' rocket scientist to see the undesirable consequences of screwing around in or outside marriage.
It used to be that screwing around only led to more children that the tribe would take care of collectively. The only bad consequences of screwing around stem from the conditions that religion has created, for example the horrible thing called "family values". The condition that created this kind of patriarchal religion is the rise of agriculture. Agriculture led to accumulation of wealth, thus inheritence, thus concern for male lines of descent, thus the taboo against screwing around. The religion was created around these pre-existing conditions. Taboos against sex before marriage are intended to control the hierarchical social structure. Having family values also means that anyone not in your family is considered less worthy of protection, except in a reluctant charity kind of way. The consequence of this is a society where it's everyone for themselves, and if you have a baby out of "wed-lock", you are screwed, cause there is no longer any tribe to help take care of it.
Because then you have the problems caused by people getting married for all the wrong reasons in the first place.
Wrong reasons, such as... wanting to get married, which is a pressure that the church creates. You can't have sex before marriage, so the sexual tension builds up to the point that dammit I NEED TO GET FUCKING MARRIED TO SOMEONE -ANYONE- OR I'M GONNA BURST!
Sin isn't just an act, it's a condition, and it's one that we're stuck with in this life.
That's the kind of mythology on which the church depends. As long as you feel you are less than perfect, you will accept the authority of an institution that claims to approach perfection. It a con. You are a devine being, that's the real gospel as taught by Jesus.
Secondly, it wasn't wisdom or knowledge that caused their shame, it was caused by a voluntary genetic alteration of their flesh, which for them and all of us turned out to be quite a disappointment.
You can't change your genes voluntarily. The fall myth is really about people getting smart, perhaps the rise of language, or the discovery of psychedelic plants. It's about how, in coming up with "solutions", (ideas, inventions, religions, etc...) we actually create more problems for ourselves.
