What is an orgasm? An orgasm is an emotional and physical experience that occurs during a “sexual response cycle”. Before an orgasm, your body becomes increasingly excited. Breathing, heart rate and blood pressure increases.

In women, the labia, clitoris, vagina and pelvic organs enlarge in very much the same way as the aroused penis enlarges.

The orgasm happens when excitement seems to go over the edge -- a climax or crescendo is reached which may last several seconds or longer. During orgasm the body stiffens and the muscles contract. Involuntary muscle contractions and spasms may occur in various parts of the body, including your legs, stomach, arms, and back. The muscles of the vagina relax and contract rapidly, as do the muscles of the uterus. The glands of the vagina (Bartholin's glands) discharge a watery secretion, which acts to lubricate the vagina.

The main physical changes that occur during a sexual experience are a result of vasocongestion. This is the accumulation of blood in various parts of the body. Muscular tension increases and other changes occur throughout your body also.
