The body of a man and especially the face is more hairy, and the voice has a different and more powerful tone. He is more courageous and energetic than woman. His brain is absolutely larger but whether or not proportionately to his larger body, has not been fully ascertained. In woman the face is rounder, the jaws and the base of the skull smaller, the outlines of the body rounder, in parts more prominent, and her pelvis is broader than in man, but his latter character may perhaps considered rather as a primary rather than a secondary sexual character. She comes to maturity at an earlier age than man. It has been found that the distinctive characters of the male sex are not fully developed until he is nearly mature. In regard to the general hairiness of the body, the women in all races are less hairy than men, and in some mammals the body of the female is less hairy than men than that of the male. These differences are not the basic ones in differentiating a man from a woman through this lesson students will be able to to know the basic difference of a man and woman in different aspects most especially one’s sexuality. Human Sexuality The French called it “the little death” because the pleasure is so intense and involving thought for a few brief s what is completely cut off from all other sensations from all perception of the rest of the world. In order to bring power of sex under control different societies have developed laws in customs which circumscribes the kind and manner of sexual behavior permitted to their members the consequences of limitation for our own society is that sex became an object of taboo-forbidden except under limited circumstances. Human sexuality is the expression of sexual sensation and related intimacy between human beings. Psychologically, sexuality is the means to express the fullness of love between a man and a woman. Biologically, it is the means through which a child is conceived and the lineage is passed on to the next generation. Sexuality involves the body, mind, and spirit; therefore, this article regards sexuality holistically and does not separate out the physiological mechanics of the reproductive system.

Human Male. Physiological, human sexuality comes from the reproductive organs. Gonads which produce sex cells, for male it is called testes or testicles. It is where the sperm is manufactured in long narrow tubes the seminiferous tubules. The sperm cell is moved through the various vessels and ducts and in the prostate gland are mixed with semen the milky alkaline fluid which is ejaculated from the penis during the orgasm. Penis, is the main organ copulation, the sensitive part is a glance known as the corona or crown of the penis. Prepuce or foreskin is the loose fold skin covered the gland. Today, the foreskin is surgically removed immediately after the birth of the male infant. This practice is the medical lingo is known as circumcision. The size of the penis differs from person to person. The length of an average penis is the placid state is from 2 and ½ to 4 inches and its diameter is about 1 inch. When erect the average penis measures between 5 and 1/2 to 6 and ½ inches, with a diameter of about an inch and ½. In other words, to smaller penises in nearly all cases had greater erective potential than the larger ones (Masters and Johnson, 1966). Release of the semen is pleasurable act in itself. When we achieve this response through nocturnal emission or wet dreams, masturbation, pitting to the climax or some other outlet (as in homosexuality) besides intercourse. Human Female. The female organs are predominantly internal. The most important ones are the vagina uterus, ovaries and fallopian tubes. The external part is the vulva, consisting the labia majora and minora, the clitoris, the openings of the urethra and the hymen. The entire system seem to be designed to receive the semen from the male to produce the ovum and to carry out the task of embryonic and fetal Republic of the Philippines CENTRAL BICOL STATE UNIVERSITY OF AGRICULTURE Impig, Sipocot, Camarines Sur 4408 Website: www.cbsua.edu.ph ISO 9001:2015 CERTIFIED Email Address: cbsua.sipocot@cbsua.edu.ph Trunkline: (054) 881 -6681 development of an infant. The labia majora or large lips consists of folds tissues somewhat covered by hair extending from the fatty pubic area to almost the rectal area. The labia minora are the inner folds less readily visible and more sensitive. It consists of erectile tissue and with its intensive covering of nerve endings can be stimulated to partial erection during the sex act. Vagina, as passageway of the menstrual discharge, as the copulatory area, and as the major part of the birth canal (Gordon, 1955). Hymen is a membranous fold perhaps half inch in diameter which partly closes the opening of the vagina. It is ruptured during the initial intercourse if this has not already occurred as a result of masturbation or some other cause. Ovaries are the female gonads and are located inside the pelvis one to the right and one to the left of the uterus or womb. Generally, a girl will experience menarche ,the onset of her first menstrual period between the ages 11 and 15. This is the sign that ovulation has started. At regular intervals most commonly 28 days one of the follicles in the ovaries burst and an ovum is ejected. The fallopian tube will be the passage between the ovary and the uterus. Concepcion will take place when one of the millions of sperm cells ejaculated during intercourse will make its way to fallopian tube. If fertilization takes place the ovum and the sperm cell become a zygote and continue down the fallopian tube and to the uterus if the ovum is not fertilized it simply passes through the uterus and it flush out through the vagina. Clitoris “unique organ in the total human anatomy” (Masters and Johnson, 1966). It is the female's centered sexual response, it is the female phallus in its the counterpart of male penis. Its purpose is to initiate or raise the level of sexual tension that is it is the organ which has no other function Republic of the Philippines CENTRAL BICOL STATE UNIVERSITY OF AGRICULTURE Impig, Sipocot, Camarines Sur 4408 Website: www.cbsua.edu.ph ISO 9001:2015 CERTIFIED Email Address: cbsua.sipocot@cbsua.edu.ph Trunkline: (054) 881 -6681 except pleasure it has many nerve endings concentrated into a small area. In fact direct manipulation of the clitoral glands may quickly turn into an irritant rather than a sexual stimulant. The Process of Human Reproduction and Sexual Pleasure Among lower forms of animals, the sex drive of the female is periodic, seasonal, and controlled to a great extent of hormones. The menstrual cycle in humans is quite different from the estrus cycle of animals. Although, it is true that the human female’s production of estrogen is highest during ovulation, this increase has no appreciable effect on her sex drive. This split between sexual pleasure and reproduction underlies the new attitudes toward sex , which are often referred to as sexual revolution. In fact the very people who advocate free sexual expression are often those who are most strenuously in favor to ZERO population growth. During sexual act, the male deposits in the vagina his sperms which move towards the fallopian tube passing through the uterus. The union of the egg cell and the sperm cell is called fertilization. After fertilization, the embryo continuous its journey to the uterus. In the womb the fetus grows and develops until the end of pregnancy which is about 280 days from the time of conception. Menstruation The rolls down the fallopian tube towards the uterus and disintegrates. The thickened lining of the uterine walls sheds off and flows out of the woman’s body in the form of bloody discharge. Normal menstrual period could last from 5 to 8 days, with 4 to 6 as the average. This is from 20 to 36 days with the average being of 28 days. For some reason the cycle may vary in length. When a woman no longer menstruates, she has arrived at what is known menopause. Phases of Menstruation Republic of the Philippines CENTRAL BICOL STATE UNIVERSITY OF AGRICULTURE Impig, Sipocot, Camarines Sur 4408 Website: www.cbsua.edu.ph ISO 9001:2015 CERTIFIED Email Address: cbsua.sipocot@cbsua.edu.ph Trunkline: (054) 881 -6681 The menses phase: This phase, which typically lasts from day one to day five, is the time when the lining of the uterus is actually shed out through the vagina if pregnancy has not occurred. Most women bleed for three to five days, but a period lasting only two days to as many as seven days is still considered normal. follicular phase: This phase typically takes place from days six to 14. During this time, the level of the hormone estrogen rises, which causes the lining of the uterus (called the endometrium) to grow and thicken. In addition, another hormone—follicle-stimulating hormone—causes follicles in the ovaries to grow. During days 10 to 14, one of the developing follicles will form a fully mature egg (ovum). Ovulation: This phase occurs roughly at about day 14 in a 28-day menstrual cycle. A sudden increase in another hormone—luteinizing hormone— causes the ovary to release its egg. This event is called ovulation. The Means of Sexual Expression The means of sexual expression Sex drives can be expressed in three basic ways: masturbation, petting and sexual intercourse. Masturbation. Many decades ago, masturbation was highly condemned by the respected authorities in Filipino society as wicked, unwholesome, a sin, and a dangerous vice. Medical and religious leaders warned parents to stop their children from masturbating at all cost. Masturbation is self-stimulation of the genitals or other erotically sensitive parts of the body for sexual arousal and orgasm (Perry, 1981). As such it may interpreted as common form of activity among humans.

The word “petting” is used to describe any sex play with a partner which does not include intercourse. The sexual activities of virgins who have not experienced sexual intercourse as involving various levels of “kissing and touching anther's body and exposing one’s own body to another for sexual pleasure without having pleasure” (Sorensen, 1973). However, if petting has a prelude to sexual intercourse, it usually know as “Foreplay”. Sexual Intercourse is a generative act, the transference of semen from the male into the reproductive tract of the female, thus allowing conception to take place. Coitus is the most accepted form of complete sexual expression, oral-genital stimulation (genital kissing) is practice today. This practice may either be fellatio or cunnilingus. Fellatio means sucking or kissing of a man’s penis while cunnilingus means kissing of a woman’s genital area. Some Sexual Problems The physiological sexual response cycle is a natural involuntary occurrence (Perry, 1981). Impotence is the inability of a man to achieve or maintain an erection long enough to perform coitus (Perry, 1981). The fault lies with a syndrome of fear and anxiety, therefore the majority of impotent cases are physiological in nature. Sexual myths and fallacies (adopted from J. L. McCary human sexuality, 2 nd ed. New York: D. Van Ostrand Company, 1973) During the menstruation, women should not engage in sports; nor should they take a bath shower, or shampoo their hair. Excellence of athletic performance is reduced by sexual intercourse the night before or the day of any athletic competition. The size of man’s penis can be judged by the size of his hand and feet. The penis of the black male is larger than that of the white male. Sex desire and ability decrease markedly after the age of 40 – 50. There is an absolutely “safe” period for sexual intercourse in which coitus can’t cause impregnation. Because of their sexual tendencies, homosexuals are more likely than heterosexuals to be disloyal to their country. The typical career woman is suppressed lesbian.

Pornography has a corruptive effect on people’s minds and behavior, specially children’s. Pornography stimulates people to commit criminal sex acts. Premature ejaculation men in our society have had their first heterosexual experience with prostitutes who are interested in finishing the act as quickly as possible so as tpo get the next customer. It can be a major problem to sexual adjustment. Orgasm dysfunction men who are impotent find release of sexual tension by masturbating or petting to orgasm (Perry, 1981). There are times when orgasmic dysfunction can be accompanied by a condition known as vaginismus, an involuntary contraction of the vagina in a response to attempted penetration. Summary The organs of human reproduction are the testes on the part of the male which produce sperm cells and ovaries on the part of the female which produce eggs. The male sex cells after being mixed with the semen in the prostate, is ejaculated through the erect penis during coitus. The female sex cells are produced in the ovaries. Once a month an ovum is released into the fallopian tube. It fertilized by a sperm, it goes into the uterus where it grows into an embryo. If not, it passes out of the body with the flow of menstrual blood. Among humans, sez is source of great pleasure as well as a method of reproduction. Unlike other animals, humans can have sex any time. The means of sexual expression are masturbation, petting and sexual intercourse. Both men and women experience sexual problems. These can cause a disruption in the normal functioning of their relationship. These include impotence, or the inability of the male to achieve an erection;premature ejaculation or the inability of the male to prolong coitus for a sufficient time to satisfy his partner; and orgasmic dysfunction or the inability to achieve orgasm which may be accompanied by the vaginismus or involuntary tightening of thevaginal canal that would not allow intromission of the penis.
