People have different opinions and ideas about normal or abnormal sexual behaviors. Sex is common all over the world and all people are interested in it. The most common disorders are homosexuality, sexual dysfunctions and sexual deviation. The only reason these disorders are unique is due to the norm established by society, but they are not necessarily abnormal (Dombeck, 2002). Sexual orientation describes patterns of sexual and romantic attraction to someone else. Normally one pole attracts the other, but in this case it doesn't work like that. There is little information about why a person's sexual orientation might deviate from what is normal. Research shows that this problem could be due to the role of genes, the environment, hormones, the way a family raised children, or the brain itself. According to Sigmund Freud, all human beings are bisexual, but become heterosexual or homosexual due to the experiences they live with their parents and other people. Psychologists and psychiatrists have a negative attitude towards homosexuality. However, there is no rule or empirical evidence to support the idea that same-sex attraction is a form of mental illness or psychopathology. Homosexuality is a matter of choice rather than an anomaly due to brain dysfunction (APA, 1975; 1987). Sexual dysfunction refers to a difficulty experienced by a couple or an individual during any phase of normal sexual activity, including desire, arousal, or orgasm. Sexual dysfunction affects both men and women at any age. This can be caused by emotional or physical problems. It could be due to lack of trust between lovers, psychological problems, depression, among other things. In men, the most important thing is extensive therapy, and with enough motivation and support, a person can be cured. People suffering from these disorders should not be alone as they will get better if they feel they have the love and support of their loved ones. Works Cited Dombeck, Mark, PhD.
