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.

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. Birth - Anatomy of Love and Sex -1981-
