Orgasm is a series of intense, pleasurable muscle contractions in the pelvic area. This is the result of genital stimulation.
Before orgasm, the body's muscles have tightened, and blood vessels in the genital area have swelled with blood. When this has reached a peak (climax), the muscles suddenly relax, and orgasm follows.
