PIP: 2 theories long held regarding female sexuality have been the Eve-out-of-Adam's Rib theory and Freud's well-known clitoral-vaginal transfer theory. Because all embryos, male and female, start life by developing a combined clitoral-penile tubercle, it seemed that all fetuses started as male and by the 3rd month the females gave up trying to grow a penis, the clitoris being the remains. Geneticists have discovered that all human embryos start life as females, as do all embryos of mammals. About the 2nd month the fetal tests elaborate enough androgens to offset the maternal estrogens and maleness develops. The discussion of clitoral vs. vaginal orgasm is meaningless because orgasm is the result of muscular stretching and fluid produced by the veins filling the fatty tissues. The process is exactly the same in males and females. From a scientific viewpoint there is only 1 kind of orgasm, the ''myovascular orgasm.'' In primates which have no foreplay, the sexual organs enlarge to the point that the blood vessels are quite distended. This especially is seen in some of the primates. Man is more like the smaller monkeys and other mammals in that foreplay is required for orgasm.
