That makes a lot of sense until you look at the evidence. In the epic of Gilgamesh, Shamhat, a sacred prostitute, has sex with Enkidu for a week before introducing him to civilization and then dipping out of his life. We have evidence of varied attitudes on sex at a cultural level around the world. In fact in the middle East we have such a clear picture of a sexually open culture that it’s a relevant question how the attitudes we see in the bible come up so close to Babylon. David Graeber argues that it’s related to the adoption of money in his book Debt, but I really feel that the schismogenetic component is more worth using for the short internet comment level explanation.
