Being knowledgeable about anatomy and physiology increases our potential for pleasure, physical and psychological health, and life satisfaction. Beyond personal curiosity, thoughtful discussions about anatomy and physiology with sexual partners reduces the potential for miscommunication, unintended pregnancies, sexually transmitted infections, and sexual dysfunctions. Lastly, and most importantly, an appreciation of both the biological and psychological motivating forces behind sexual curiosity, desire, and the capacities of our brains can enhance the health of relationships.

Most people are curious about sex. Google processes over 3. What are the most frequently asked questions concerning sex on Google? Are they about extramarital affairs? Kinky fantasies? Sexual positions? Surprisingly, no.

For example, when Buhi and colleagues examined the content of sexual-health websites, they found that nearly half contained inaccurate information. How about we—the authors of this module—make you a promise? Even though this module is about a fascinating topic—sex—it contains vocabulary that may be new or confusing to you. Learning this vocabulary may require extra effort, but if you understand these terms, you will understand sex and yourself better. Although people have always had sex, the scientific study of it has remained taboo until relatively recently. Masters was a former Navy lieutenant, married father of two, and trained gynecologist with an interest in studying prostitutes.

Johnson was a former country music singer, single mother of two, three-time divorcee, and two-time college dropout with an interest in studying sociology. And yes, if it piques your curiosity, Masters and Johnson were lovers when Masters was still married ; they eventually married each other, but later divorced. Despite their colorful private lives they were dedicated researchers with an interest in understanding sex from a scientific perspective.

They measured more than 10, orgasms in individuals 18 to 89 years of ageduring sex with partners or alone. Their initial experimental techniques and data form the bases of our contemporary understanding of sexual anatomy and physiology. Sexual anatomy is typically discussed only in terms of reproduction see e.

Full discussions of sexual anatomy also include the concept of pleasure. Thus, we will explore the sexual anatomies of females see Figures 1a and 1b and males see Figure 2 in terms of their capabilities for both reproduction and pleasure. Many people find female sexual anatomy curious, confusing, and mysterious. This may be because so much of it is internal inside the bodyor because—historically—women have been expected to be modest and secretive regarding their bodies. Perhaps the most visible structure of female sexual anatomy is the vulva.

The primary functions of the vulva are pleasure and protection. It includes many parts:. The minor VGs—also called Skene's glands not picturedare on the wall of the vagina and are associated with female ejaculation, and mythologically associated with the G-Spot Kilchevsky et al. The major VGs—also called Bartholin's glands—are located just to the left and right of the vagina and produce lubrication to aid in sexual intercourse.

Extending foreplay and using commercial water- silicone- Adult searching orgasm San Antonio Texas oil-based personal lubricants are simple solutions to this common problem. The clitoris and vagina are considered parts of the vulva as well as internal sex organs see Figure 1b. They are the most talked about organs in relation to their capacities for female pleasure e.

The visible parts—the glans and prepuce—are located above the urethra and the labia minora at Adult searching orgasm San Antonio Texas pinnacle. Second, there is the outer one-third of the vagina anterior wall. It is formed during the second trimester of pregnancy and is generally more sensitive than the inner portion, but dramatically less sensitive than the clitoris Hines, At each end of the vagina are the cervix the lower portion of the uterus and the introitus the vaginal opening to the outside of the body.

The vagina acts as a transport mechanism for sperm cells coming in, and menstrual fluid and babies going out. A healthy vagina has a pH level of about four, which is acidic. When the pH level changes, often due to normal circumstances e.

This potential problem can be solved with over-the-counter vaginal gels or oral probiotics to maintain normal vaginal pH levels Tachedjiana et al. The primary functions of the internal sex organs of the female are to store, transport, and keep ovum cells eggs healthy; and produce hormones see Figure 1b.

These organs include:. These tubes allow for ovulation about every 28 dayswhich is when ova travel from the ovaries to the uterus. If fertilization does not occur, menstruation begins. The most prominent external sex organ for the male is the penis.

On average, a flaccid penis is about three and a half inches in length, whereas an erect penis is about five inches Veale et al. The penis has three parts: the root, shaft, and glans. Foreskin covers the glans, or head of the penis, except in circumcised males.

The glans penis is highly sensitive, composed of more than 4, sensory-nerve endings, and associated with initiating orgasms Halata, Lastly, it has the urethral opening that allows semen and urine to exit the body. In addition to the penis, there are other male external sex organs that have two primary functions: producing hormones and sperm cells.

The scrotum is the sac of skin behind and below the penis containing the testicles. The testicles or testes are the glands that produce testosterone, progesterone, small amounts of estrogen, and sperm cells. Many people are surprised to learn that males also have internal sex organs. The primary functions of male internal sex organs are transporting sperm cells, keeping sperm cells healthy, and producing semen —the fluid in which sperm cells are transported. At first glance—or touch for that matter—the clitoris and penis are the parts of our anatomies that seem to bring the most pleasure.

Extensive regions of the brain and brainstem are activated when a person experiences pleasure, including: the insula, temporal cortex, limbic system, nucleus accumbens, basal ganglia, superior parietal cortex, dorsolateral prefrontal cortex, and cerebellum see Figure 3, Ortigue et al. Neuroimaging techniques show that these regions of the brain are active when patients have spontaneous orgasms involving no direct stimulation of the skin e.

Erogenous zones are sensitive areas of skin that are connected, via the nervous system, to the somatosensory cortex in the brain. The somatosensory cortex SC is the part of the brain primarily responsible for processing sensory information from the skin.

The more sensitive an area of your skin is e. A study by Nummenmaa and his colleagues used a unique method to test this hypothesis. The Nummenmaa research team showed experimental participants images of same- and opposite-sex bodies. They then asked the participants to color the regions of the body that, when touched, they or members of the opposite sex would experience as sexually arousing while masturbating or having sex with a partner.

The SRC is composed of four phases:. Further, a partner or environmental object is sufficient, but not necessary, for the SRC to occur. One of the potential outcomes of the SRC is pregnancy —the time a female carries a developing human within her uterus. How does this happen? The process begins during vaginal intercourse when the male ejaculates, or releases semen. Each ejaculate contains about million sperm cells. These sperm compete to Adult searching orgasm San Antonio Texas their way through the cervix and into the uterus. Conception typically occurs within a fallopian tube when a single sperm cell comes into contact with an ovum egg.

The sperm carries either an X- or Y-chromosome to fertilize the ovum—which, itself, usually carries an X-chromosome. The combination of two X chromosomes produces a female zygote fertilized ovum. The combination of an X and Y chromosome produces a male zygote. XX- or XY-chromosomes form your 23rd set of chromosomes most humans have a total of 46 chromosomes commonly referred to as your chromosomal sex or genetic sex. Interestingly, at least 1 in every 1, conceptions in a variation of chromosomal sex beyond the typical XX or XY sets. In some cases, people may have unusual physical characteristics, such as being taller than average, having a thick neck, or being sterile unable to reproduce ; but in many cases, these individuals have no cognitive, physical, or sexual issues Wisniewski et al.

Almost 15 out of every 1, births are multiple births twins, triplets, quadruplets, etc. These can occur in a couple of ways. Dizygotic fraternal births are the result of a female releasing multiple ova of which more than one is fertilized by sperm. Because sperm carry either X or Y chromosomes, fraternal births can be any combination of sexes e.

They develop together in the uterus and are usually born within minutes of one another. Monozygotic identical births result from a special circumstance in which a fertilized ovum splits into multiple identical embryos and they develop simultaneously. Identical twins are, therefore, the same sex. Hours after conception, the zygote begins dividing into additional cells. It then starts traveling down the fallopian tube until it enters the uterus as a blastocyst.

However, the percentage of successful implantations remains a mystery.
