Orgasm is the conclusion of the plateau phase of the sexual response cycle, shared by
men and women alike. During orgasm, both men and women experience quick cycles of muscle
contraction in the lower pelvic muscles, which surround both the anus and the primary sexual
organs.
Orgasms in both men and women are often associated with other involuntary actions, including vocalizations and muscular spasms in other areas of the body. Also, a generally euphoric sensation is associated with orgasm.
