A quote from the concluding paragraphs of the book, He Comes Next by Ian Kerner:
Sex is the one place where, if there's enough love and trust in the other person's genuine desire, the sheer pleasure of letting go can be experienced in a concert of all the senses, which is not only sexually cathartic, but can be emotionally bonding in a way unparalleled by any other form of human interaction.
See how such writers conform to the taboos of prudery and obsfucation ? "Making Love" is a bit more warm and tender than the sterile brutal mating words of sex and fuck. "Letting Go" fits rope climbing and loosening a sphincter muscle enough to fffffffttttt out colon gas. Science provides coitus precision for how penis and vagina interact. THRUSTING approximates "male performance" with a partner. Few writers like Henry Miller with wife and Anais Nin spun novels into the expanding vocabulary for passion appetite and describing how lovers connect skin tongue eyes nose ears and "souls" intimately....Professor Marston tried to elevate women and polyamory over patriarchal fascism modeling Wonder Woman after the niece of Margaret Sanger and his Radcliffe Professor spouse both women gave him son/s and the 3 perfected the lie detector for truth in relationships NOT VALIDATING COURTROOM testimony
