✽ is a multidimensional concept. ✽ It can be defined broadly by stating that sexuality integrates the somatic (bodily), emotional, intellectual, & social aspects of being a human sexual being. ✽ It involves the anatomy & physiology of the human body, as well as one’s attitudes & feelings about oneself ❇ Biologic gender – is the term used to denote chromosomal sexual development: male (XY) or female (XX) ❇ Gender / sexual identity – is the inner sense a person has of being male or female ❇ Gender role – is the behavior a person conveys about being a male or female. COMPONENTS OF SEXUALITY 1. Reproductive Sexuality -involves the biological aspects of conception & procreation. It also includes the sexual response 2. Gender Sexuality -deals w/ the social & emotional aspects of being a man or a woman. 3. Erotic Sexuality -refers to sexual love and arousing sexual desires ❇Heterosexuality – one who finds sexual fulfillment with a member of opposite gender ❇ Homosexuality – a person who finds sexual fulfillment with a member of his or her own sex. - usually they prefer to be called as “gay” for men & “lesbian” for women ❇ Bisexuality – people are bisexual if they achieve sexual satisfaction from both homosexual and heterosexual relationship ❇ Transexuality – is an individual who, although one biologic gender, feels as is he or she should be of the opposite gender -sex change operations (synthetic vagina/penis) ❇ Celibacy – abstinence from sexual activity. -the ability to concentrate on the means of giving and receiving love other than through sexual expressions. ❇ Transvestism – individual who dresses to take on the role of the opposite sex ❇ Voyeurism – sexual arousal by looking at another’s body. Almost all children and adolescents pass through a stage when voyeurism is appealing. ❇ Sadomasochism – involves inflicting pain (sadism) or receiving pain (masochism) to achieve sexual satisfaction ❇ Masturbation – self-stimulation for erotic pleasure. - Children between ages 2 to 6 years discover masturbation as an enjoyable activity as they explore their bodies. ❇ Exhibitionism – revealing one’s genitals in public. ❇ Pedophiles – interested in sexual encounters with children. ❇ Erectile Dysfunction –formerly referred to as impotence - inability to produce or maintain an erection long enough for vaginal penetration or partner satisfaction. ❇ Premature Ejaculation – ejaculation before penile contact. - can be unsatisfactory and frustrating to both partners - can be psychological ❇ Failure to achieve orgasm - can be due to poor sexual technique - or possible negative attitudes toward sexual relationships ❇ Vaginismus – involuntary contraction of the muscles at the outlet of the vagina when coitus is attempted. - This muscle contraction prohibits penile penetration. ❇ Dyspareunia – pain during coitus - can be due to endometriosis ❇ Inhibited Sexual Desire – lack of desire for sexual relations may be a concern of young or middle- aged adults. Support or a caring sexual partner or relief of the tension causing the stress allows a return to sexual interest. HUMAN SEXUAL RESPONSE  Sexuality has always been a part of human life, but it is only in the past few decades that it has been studied scientifically. One common finding of researchers has been that feelings and attitudes about sex vary widely: the sexual experience is unique to each individual, but sexual physiology (i.e., how the body responds to sexual arousal) has common features. Excitement  occurs with physical and psychological stimulation (i.e., sight, sound, emotion, or thought) that causes parasympathetic nerve stimulation. This leads to arterial dilation and venous constriction in the genital area. The resulting increased blood supply leads to vasocongestion and increasing muscular tension.  In women, this vasocongestion causes the clitoris to increase in size and mucoid fluid to appear on vaginal walls as lubrication. The vagina widens in diameter and increases in length. The nipples become erect.  In men, penile erection occurs, as well as scrotal thickening and elevation of the testes. In both sexes, there is an increase in heart and respiratory rates and blood pressure. Plateau  The plateau stage is reached just before orgasm. In the woman, the clitoris is drawn forward and retracts under the clitoral prepuce; the lower part of the vagina becomes extremely congested (formation of the orgasmic platform), and there is increased nipple elevation.  In men, the vasocongestion leads to distention of the penis. Heart rate increases to 100 to 175 beats per minute and respiratory rate to approximately 40 respirations per minute. Orgasm  Orgasm occurs when stimulation proceeds through the plateau stage to a point at which the body suddenly discharges accumulated sexual tension. A vigorous contraction of muscles in the pelvic area expels or dissipates blood and fluid from the area of congestion. The average number of contractions for a woman is 8 to 15 contractions at intervals of 1 every 0.8 seconds.  In men, muscle contractions surrounding the seminal vessels and prostate project semen into the proximal urethra. These contractions are followed immediately by three to seven propulsive ejaculatory contractions, occurring at the same time interval as in the woman, which force semen from the penis. Resolution  Resolutionis a 30-minute period during which the external and internal genital organs return to an unaroused state.  For the male, a refractory period occurs during which further orgasm is impossible.  Women do not go through this refractory period, so it is possible for women who are interested and properly stimulated to have additional orgasms immediately after the first.
