I think it was Eve who is responsible for women having the burden of bearing children, biblically speaking. Whether Biblically or through the natural selection process of nature, genders have specific roles. Nature created the double standard and the idealistic thinking of humans cannot and should not attempt to believe they are wiser than the laws of nature.
I think if women want to be promiscuous and attempt lower themselves to the behavior of men, they must be able to accept the consequences. Nature gave women the greater responsibility, which means the women should be more responsible concerning who they lay with and as a general rule, they are.
A person only has 50% control over any one-on-one relationship of equals. That 50% control is of themselves. However, a woman incubates and brings forth life through the womb, meaning that she has more than a 50% stake in a one-on-one sexual encounter. She has the stake of the child born from the gift/burden that nature affixed to her.
Women should not make a sexual decision based upon expectations of what a man [should] do. Again, she has no control over what the many [will] do, but she has total control over what she will do, assuming self-control. Given empirical evidence of the behavior of men a woman who lays with a man is taking a much greater risk than a man takes when he lays with a women.
A promiscuous man only risks a sexual transmitted disease. A promiscuous women risk, STDs, pregnancy and caring for a child because of the bond formed between mother and child in the womb. It is much easier for a man to walk away from a child when they have not bonded with them. Women have the bond formed in the womb. Consequently, should be more responsible because their risks are simply greater.
