We are, each of us, born from an act of love (or at least, an act of sex). And we spend the rest of our lives seeking a love that feels like that first, primal safety—the warm, rhythmic, oxytocin-soaked memory of being held skin-to-skin, hearing a heartbeat, and knowing, before language, that we are safe.
The caesarean section rate in the US was rising (hitting nearly 18% by 1981, up from 5% in 1970). Critics argued that the supine position (lying on the back, which compresses the sacrum and narrows the pelvic outlet) was not just bad obstetrics but bad sex. You cannot make love or birth a baby effectively lying flat on your back with your legs in stirrups.
And 1981 was the year modern science finally drew the connecting lines. Birth - Anatomy of Love and Sex -1981-
The perineum, the 1981 anatomists argued, is designed to stretch. Its collagen fibers, under the influence of the hormone relaxin (discovered decades earlier but fully characterized by 1981), can become pliable. A perineum that stretches naturally during birth—lubricated by blood, sweat, and amniotic fluid—retains its innervation (nerve supply). That innervation is precisely what allows for the exquisite sensitivity of the vaginal introitus during intercourse.
In the vast library of human understanding, certain years act as pivot points—moments when a cluster of ideas coalesces into a new paradigm. The year 1981 stands as one such landmark. It was a year wedged between the free-love ethos of the 1970s and the AIDS-conscious sobriety of the mid-80s. Yet, beneath the surface of political shifts and pop music, 1981 witnessed a quiet revolution in how we understand the most fundamental acts of human existence: Birth , Love , and Sex . We are, each of us, born from an
This had direct implications for the couple’s sexual relationship. The 1981 sex therapists noted that couples who birthed together (with the father as a calm, informed coach) reported re-establishing intercourse faster than those from whom the father was excluded. The shared trauma-to-triumph of birth became a form of "limbic bonding" that deepened marital sex. In the anatomy of love, the breast is the most polyvalent organ. In 1981, the debate over breastfeeding was at its most politicized (the first WHO code on marketing breast-milk substitutes was adopted that year). But the anatomy was clear.
The nipple-areola complex is rich in sensory nerve endings—Meissner’s corpuscles and free nerve endings identical to those in the clitoris and glans penis. Suckling triggers the same hypothalamic response as genital stimulation. Critics argued that the supine position (lying on
Third, the cultural conversation around sex was finally admitting that female pleasure was not a luxury but a biological driver. The 1977 publication of Our Bodies, Ourselves had set the stage, but by 1981, the clitoris was no longer a hidden secret; it was being mapped in anatomy textbooks as the anatomical twin of the penis, sharing the same embryological origins.
