The clitoris is a female genital organ. It includes erectile tissue, glands, muscles and ligaments, nerves, and blood vessels. In an embryo there is a small raised point that grows into a clitoris in girls or a penis in boys. Inside the penis, there is the urethra, but there is no urethra in the clitoris. In women, the urethra is hidden behind the clitoris and in front of the vagina. Penises with male urethras are used daily for urination, and can be used for sex: semen passes out of the body through the male urethra.
Although the parts are placed differently, the clitoris is a match to the male penis. The clitoris causes females sexual pleasure, arousal and orgasm. Rubbing or applying other consistent pressure to it is usually needed to help the female have an orgasm.[2][3][4][5]
During sexual arousal, erectile tissue fills with blood. This causes the clitoris to grow. It grows until orgasm happens. Also during arousal, touching the clitoris and other sensitive areas of the female genitals makes a woman's vagina change shape and release a lubricant. The lubricant and change of shape makes it easier for a man's penis to enter a woman and for sex to occur. Most of the clitorial body is hidden inside the hood, but only a small part of it may be seen outside the body. Adding the outside and inside parts, the clitoris is about the same size as the penis. The clitoris and penis grow from the same tissue in the womb; they bear many similar parts.
