What is an orgasm? It is series of involuntary muscle contractions in the anus, lower pelvic muscles, and sexual organs, accompanied by a sudden release of endorphins providing a feeling of euphoria. Orgasm is preceded by moistening of the vaginal walls and enlargement of the clitoris. The clitoris moves inward under the clitoral hood. The vagina decreases in size by about a third. There are rhythmic and pulsating contractions of the uterus, vagina and pelvic muscles. After orgasm, the clitoris emerges from under the clitoral hood and returns to normal size.

It is situated about inches inside the vagina, on the front wall. This gland can be stimulated during sexual activity; it swells with fluids and begins to feel bumpy.
