There is, of course, individual variation in the sensitivity of these areas. Types of Sexual orientation  Heterosexuality  Homosexuality  Bisexuality  Transexuality  Types of sexual expression 1.Celibacy 2.Masturbation 3.Erotic stimulation 4.Fetishism 5.Transvestism 6.Voyeurism 7.Sadomasochism 8.Exhibitionism 9.Phidophiles Deviant Sexual Behavior 1.

Excitement phase marked by increase in pulse and blood pressure, an increase in blood supply to the surface of the body resulting in increased skin temperature, flushing, and swelling of all distensible body parts (particularly noticeable in the penis and female breasts), more rapid breathing, the secretion of genital fluids, vaginal expansion, and a general increase in muscle tension. Phases of Sexual Response/Cycle 2. Plateau phase, which is generally of brief duration. If stimulation is continued, orgasm usually occurs. Orgasm is marked by a feeling of sudden intense pleasure, an abrupt increase in pulse rate and blood pressure, and spasms of the pelvic muscles causing vaginal contractions in the female and ejaculation by the male. Involuntary vocalization may also occur. Orgasm lasts for a few seconds Phases of Sexual Response/Cycle 3. Orgasmic phase This phase is the climax of the sexual response cycle. It is the shortest of the phases and generally lasts only a few seconds. Phases of Sexual Response/Cycle 4. Resolution phase, the return to a normal or subnormal physiological state. Up to the resolution phase, males and females are the same in their response sequence, but, whereas males return to normal even if stimulation continues, continued stimulation can produce additional orgasms in females. Stages of Love 1.Lust When you’re in the stage of lust, you feel physically attracted and drawn to the object of your affection. You want to seduce them or be seduced. There may be an element of mystery or an intensity that makes things exciting. Imagine a hot one night stand! Lust is driven by the hormones testosterone in men and estrogen in women. Lust occurs across species and may be part of the basic drive to find a partner to spread our genes with. But lust is different than love. Injecting men with testosterone makes them desire a potential lover more, but not necessarily fall in love in any lasting way. Stages of Love 2. Attraction In the second stage, you begin to obsess about your lover and crave his presence. Your heart races and you don’t feel like sleeping or eating. You may even get sweaty palms. You feel a surge of extra energy and excitement as you fantasize about the things you’ll do together. These feelings are created by three chemicals: norepinephrine, dopamine, and ser otonin.  Dopamine - Increased dopamine is associated with motivation, reward, and goal-directed behavior, hence the drive to pursue your loved one or create them in fantasy if you can’t be with them. Dopamine also creates a sense of novelty. Your loved one seems exciting, special and unique to you and you want to tell the world about his special qualities.  Norepinephrine - Norepinephrine is responsible for the extra surge of energy and racing heart that you feel, as well as the loss of appetite and desire for sleep. It puts your body into a more alert state in which you are ready for action.  Serotonin - Scientists think serotonin probably decreases at this stage, but more studies need to be done. Low levels of serotonin are found in obsessive- compulsive disorder (OCD) and are thought to cause obsessive thinking. In one Italian study of 60 students, those who were recently in love and those with OCD both had less serotonin transporter protein in their blood than regular (not recently in love) students. Stages of Love 3. Attachment Attachment involves wanting to make a more lasting commitment to your loved one. This is the point at which you may move in together, get married, and/or have children. After about 4 years in a relationship, dopamine decreases, and attraction goes down. If things are going well, it gets replaced by the hormones oxytocin and vasopressin, which create the desire to bond, affiliate with, and nurture your partner. You want to cuddle and be close and share your deepest secrets with her. You plan and dream together.  Oxytocin - Oxytocin is a hormone released during orgasm (and during childbirth and breast- feeding). This may be the reason why sex is thought to bring couples closer together and be the “glue” that binds the relationship. There is a dark side to oxytocin as well. It seems to play a role in needy, clinging behaviors and jealousy.  Vasopressin - Scientists learned about the role of vasopressin in attachment by studying the prairie vole, a small creature that forms monogamous bonds like humans do. When male prairie voles were given a drug that suppresses vasopressin, they began neglecting their partners and not fighting off other male voles who wanted to mate with her. Terms to remember  Genitals  FALLOPIAN TUBES  Androgens Uterus  Estrogens  Cervix  Progesterones  Vagina  SEMEN  Clitoris  Ovulation  Scrotum  Testoterone  Testicles or Testes  Ejaculation  Sperm  Implantation  Prostate Gland  Pituitary glands  Penis
