Ejaculation
Female ejaculation is the expulsion of fluid by human females from the para-urethral ducts through and around the urethra during or before an orgasm. It is also known colloquially as gushing or squirting, although these are considered to be different phenomena in some research publications.
Orgasm
Orgasm (sexual climax) is the sudden discharge of accumulated sexual tension during the sexual response cycle, resulting in rhythmic muscular contractions in the pelvic region characterized by an intense sensation of pleasure. Experienced by females as well as men, orgasms are controlled by the involuntary or autonomic nervous system. They are often associated with other involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation and, frequently, body movements and vocalizations are expressed. The period after orgasm (known as a refractory period) is often a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin, as well as endorphins.
Female orgasms usually result from the stimulation of the clitoris located upper side of vagina. Sexual stimulation can be by self-practice (masturbation) or by or with a sex partner (penetrative sexual intercourse, non-penetrative sex, and other erotic sexual activity).
