Document Summary
Sex anatomy and physiology, female sex organs. The female anatomy in their genital region, from anterior to posterior, is the clitoris, urinary opening, vaginal opening, and anus. The clitoris is very sensitive to touch, hence it plays an important part of sexual arousal and orgasm. The vaginal opening leads to the internal reproductive organs. It is the orifice of choice for most heterosexual intercourse, and it is also the birth canal. The vaginal opening is initially partially covered by the hymen. The hymen is ruptured during a woman"s first intercourse. It can also be ruptured by athletic activity. This means the absence of a hymen is not necessarily an indication of lost virginity: male sex organs. Male organs in the genital area going anterior to posterior are the penis, testicles, and anus. At the head of the penis is the opening for the urethra, which serves for both the voiding of urine and ejaculation of semen.
