Document Summary
Ultrasound recording have discovered that male fetuses have erections months before they are born. After birth, baby boys often have erections before the umbilical cord is cut. Baby girls can have vaginal lubrication in the 1st 24 hours after birth. As soon as infants gain sufficient control over their movements, they begin to touch all parts of their bodies: as part of this exploration, infants also touch their genitals. Infant boys and girls may continue to stimulate themselves o. Happens because the nerve ending in the genitals are already developed at birth and transmit sensations of pleasure when stimulated o. Infants do not comprehend adult sexual behavior; their behavior is aimed at finding pleasurable physical sensations, not expressing sexual desire. Initial genital self-stimulation may be random but once discovered as a pleasure component, such stimulation quickly becomes purposeful. Bodily exploration before the age of 2 is confined mainly to exploration.
