The fear of not being able to reach orgasm actually interferes with and extinguishes a woman's sexual excitement. The result is that women are even less able to relax, enjoy sex, and achieve orgasm. In her new book "On Female Orgasm," Roy, a professor of philosophy at Indiana University, points out that orgasm is a "bonus" in sexual life, and one cannot say that women who have not experienced the thrill and tremors are "incomplete." Roy believes there is a misunderstanding that both men and women need to clarify: the lack of orgasm does not mean poor sexual life. "Orgasm does not equal sexual satisfaction."
