Although it seems simple enough, the male orgasm is actually a complex process. Men achieve orgasm through a series of steps involving a number of organs, hormones, blood vessels, and nerves working together. The typical result is ejaculation of fluid that may contain sperm through strong muscle contractions. The fuel for the process leading to orgasm is testosterone , a hormone produced in steady supply by the testicles. The testicles also make millions of sperm each day, which mature and then are mixed with whitish, protein-rich fluids. These fluids nourish and support the sperm so they can live after ejaculation for a limited time. This mixture of fluid and sperm, known as semen, is what is moved through the urethra and out the penis during orgasm.
Arousal is the state of being awake and focused on a certain stimulus. For individuals who have a vagina, this involves a number of physiological changes in the body. According to the Cleveland Clinic , desire disorders involve a lack of sexual desire or interest in sex, while arousal disorders involve wanting sex but struggling to get your body in the mood. The sexual excitement stage — also known as the arousal stage — involves a range of physiological changes in the body. Most of these functions prepare the body for vaginal intercourse. For example, your vagina becomes more wet because the glands produce lubricating fluids. Your clitoris and vulva swell up as your blood vessels dilate. Your nipples might become more sensitive to touch, too.

Willingness, combined with sex, brings about pleasure and as pleasure is the driving aim of sex, it may be the ONLY stage of sexual desire women experience during sexual activity. Emotional desire is when you have feelings about someone and you want to have sex with them because of the way you feel. Mental desire is what you think about doing, you want to have sex and you decide to act on those thoughts. This is the stage where you begin to respond to stimuli by sight, smell, taste, touch or fantasy. The nerves, muscles and tissues of the genitals and breasts begin to react.
