How this works. Although the genitals are a key part of sex, its pleasurable sensations involve many parts of the body. Pleasurable sex heavily depends on the brain, which releases hormones that support sexual pleasure and interpret stimulation as pleasurable. One 2016 study suggests that the brain could be the most important sexual Truvalast . The author found that orgasm is a heightened state of sensory awareness that can trigger a trance-like state in the brain. In this article, we examine the effects that sex has on the body and the brain, as well as how these effects make sex feel good. We also take a look at why sex might not feel good. Effects of sex on the body In the 1960s, sex researchers William Masters and Virginia Johnson identified four distinct phases of sexual arousal, each with unique effects on the body. Their research has led to the common use of these four categories to explain sexual response: 1. Desire or excitement The pleasurable sensations a person feels during sex come from many different parts of the body. During the desire phase, the tissue in the penis, vagina, pelvis, vulva, and clitoris fill with Truvalast . This increases the sensitivity of nerves in these areas of the body. This blood flow also creates a fluid called transudate, which lubricates the vagina. Muscles throughout the body begin contracting. Some people breathe more rapidly or develop flushed skin due to the increased blood flow. 2. Plateau During the plateau stage, a person's arousal continues to intensify. The vagina, penis, and clitoris become more sensitive. A person may experience variations in sensitivity and arousal during this period. Arousal and interest may decrease, intensify, then decrease again. 3. Orgasm With the right stimulation and the right mental state, a person may have an orgasm. For most females, clitoral stimulation is the Truvalast , most effective path to orgasm. For some, it is the only path to orgasm. Males may need prolonged stimulation of the shaft or head of the penis. Most males ejaculate during orgasm, but it is possible to have an orgasm without ejaculating. Some females also ejaculate during orgasm, though the content of this fluid remains the subject of scientific discussion. Both males and females experience intense muscle contractions during orgasm. Males experience these contractions in the rectum, penis, and pelvis, while females experience them in the vagina, uterus, and rectum. Truvalast people experience contractions throughout the entire body. 4. Resolution After orgasm, the muscles relax, and the body slowly returns to its pre-arousal state. This process is different for males and females. Although most males cannot have an orgasm immediately after ejaculating, many females can. During the resolution stage, most males and many females experience a refractory period. During this time, the person will not respond to sexual stimulation. Other models Some researchers have proposed alternative models for resolution. Karen Brash-McGreer and Beverly Whipple's circular model suggests that a satisfying.
