The 'radical' feminists have probably got more right than wrong.

Sex was nature's trade for death. It is the tool used to accelerate evolution and Life's ability to adapt to environmental challenges.

The pleasure is what we get in exchange for dying faster and clearing the way for the next iteration.

Nature wants us to have sex.

How we design and accept our mechanisms of profit and exploitation around those desires depends on our ability to question beliefs and to understand science, as well as our ability to love without being exploited by our systems.

Any powerful instinct will be exploited in us. Human nature is not all that complicated. Our System of systems, however, makes us vulnerable to our own decency as well as our aggressions.
