A person’s sexual attraction to another, the passion and love that follows are deeply associated with the intimate happiness which is determined by anatomy, physiology, living style, relationship with the other person and developmental experience throughout the life. Normal sexual behaviour brings pleasure to oneself and one’s partner, involves stimulation of the primary sex organs including coitus; it is devoid of inappropriate feelings of guilt or anxiety and is not compulsive.
The essential feature of the sexual dysfunctions is inhibition in one or more of the phases, including disturbance in the subjective sense of pleasure or desire or in the objective performance. Either type of disturbance can occur alone or in combination. They can be lifelong or acquired, generalized or situational, and result from psychological factors, physiological factors, or combined factors. Sexual disorders can lead to or result from relational problems, and patients invariably develop an increasing fear of failure and self-consciousness about their sexual performance. Sexual dysfunctions are frequently associated with other mental disorders, such as depressive disorders, anxiety disorders and personality disorders etc. Sexual function can be adversely affected by stress of any kind, by emotional disorders, or by ignorance of sexual function and physiology. The dysfunction may be lifelong or acquired that is, it can develop after a period of normal functioning. The dysfunction may be generalized or limited to a specific partner or a certain situation.
