Three social psychological theories include: the self-perception theory, the overjustification hypothesis, and the insufficient justification hypothesis:

Self-perception theory: people make attributions about their own attitudes, feelings, and behaviours by relying on their observations of external behaviours and the circumstances in which those behaviours occur
Overjustification hypothesis: when an external reward is given to a person for performing an intrinsically rewarding activity, the persons intrinsic interest will decrease
Insufficient justification: based on the classic cognitive dissonance theory (inconsistency between two cognitions or between a cognition and a behavior will create discomfort), this theory states that people will alter one of the cognitions or behaviours to restore consistency and reduce distressThe importance of how a woman perceives her behavior should not be underestimated. Many women perceive sex as a chore as opposed to a pleasurable experience, and they tend to consider themselves sexually inadequate, which in turn does not motivate them to engage in sexual activity. Several factors influence a womens perception of her sexual life. These can include race, gender, ethnicity, educational background, socioeconomic status, sexual orientation, financial resources, culture, and religion. Cultural differences are also present in how women view menopause and its impact on health, self-image, and sexuality. A study found that African American women are the most optimistic about menopausal life; Caucasian women are the most anxious, Asian women are the most inhibited about their symptoms, and Hispanic women are the most stoic.About one-third of the women experienced sexual dysfunction, which may lead to these womens loss of confidence in their sexual lives.
For a diagnosis, the patient must have a chronic history of premature ejaculation, poor ejaculatory control, and the problem must cause feelings of dissatisfaction as well as distress for the patient, the partner, or both.Premature ejaculation has historically been attributed to psychological causes, but newer theories suggest that premature ejaculation may have an underlying neurobiological cause that may lead to rapid ejaculation. Post-orgasmic disorders
Post-orgasmic disorders cause symptoms shortly after orgasm or ejaculation. Post-coital tristesse (PCT) is a feeling of melancholy and anxiety after sexual intercourse that lasts for up to two hours. Sexual headaches occur in the skull and neck during sexual activity, including masturbation, arousal or orgasm. In men, POIS causes severe muscle pain throughout the body and other symptoms immediately following ejaculation. These symptoms last for up to a week. Some doctors speculate that the frequency of POIS "in the population may be greater than has been reported in the academic literature", and that many with POIS are undiagnosed.POIS may involve adrenergic symptoms: rapid breathing, paresthesia, palpitations, headaches, aphasia, nausea, itchy eyes, fever, muscle pain and weakness, and fatigue. The etiology of this condition is unknown; however, it is believed to be a pathology of either the immune system or autonomic nervous systems. It is defined as a rare disease by the NIH, but the prevalence is unknown. It is not thought to be psychiatric in nature, but it may present as anxiety relating to coital activities and thus may be incorrectly diagnosed as such.
