===Orgasm disorders===

==== Anorgasmia ====
{{Main|Anorgasmia}}
[[Anorgasmia]] is classified as persistent delays or absence of orgasm following a normal sexual excitement phase in at least 75% of sexual encounters.<ref name="Nolen">{{cite book| vauthors = Nolen-Hoeksema S |title=Abnormal Psychology|date=2014|publisher=McGraw-Hill|isbn=978-1-259-06072-4|location=New York|pages=|author-link=Susan Nolen-Hoeksema}}</ref>{{rp|368}} The disorder can have physical, psychological, or pharmacological origins. [[SSRI]] antidepressants are a common pharmaceutical culprit, as they can delay orgasm or eliminate it entirely. A common physiological cause of anorgasmia is [[#menopause|menopause]]; one in three women report problems obtaining an orgasm during sexual stimulation following menopause.<ref>{{cite book [[Susan Nolen-Hoeksema|Nolen-Hoeksema S]] | date = 2013 | edition = 6th | chapter = Sexual Dysfunctions. | title = Abnormal Psychology | publisher = McGraw Hill Education | page = 368 }}</ref>

====Premature ejaculation====
{{Main|Premature ejaculation}}

Premature ejaculation is when ejaculation occurs before the partner achieves orgasm, or a mutually satisfactory length of time has passed during intercourse. There is no correct length of time for intercourse to last, but generally, premature ejaculation is thought to occur when ejaculation occurs in under two minutes from the time of the insertion of the penis.<ref name="pmid9638953">{{cite journal | vauthors = Waldinger MD, Berendsen HH, Blok BF, Olivier B, Holstege G | title = Premature ejaculation and serotonergic antidepressants-induced delayed ejaculation: the involvement of the serotonergic system | journal = Behavioural Brain Research | volume = 92 | issue = 2 | pages = 111–8 | date = May 1998 | pmid = 9638953 | doi = 10.1016/s0166-4328(97)00183-6 | s2cid = 23494410 }}</ref> 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.<ref name="Diaz">{{cite journal | vauthors = Diaz VA, Close JD | title = Male sexual dysfunction | journal = Primary Care | volume = 37 | issue = 3 | pages = 473–489 | date = September 2010 | pmid = 20705194 | doi = 10.1016/j.pop.2010.04.002 | publisher = [[Elsevier]] }}</ref>

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.<ref name="pmid15215881">{{cite journal | vauthors = Laumann EO, Nicolosi A, Glasser DB, Paik A, Gingell C, Moreira E, Wang T | title = Sexual problems among women and men aged 40-80 y: prevalence and correlates identified in the Global Study of Sexual Attitudes and Behaviors | journal = International Journal of Impotence Research | volume = 17 | issue = 1 | pages = 39–57 | date = 2005 | pmid = 15215881 | doi = 10.1038/sj.ijir.3901250 | s2cid = 13187709 | doi-access = free }}</ref>

====Post-orgasmic disorders====
Post-orgasmic disorders cause symptoms shortly after [[orgasm]] or [[ejaculation]]. [[Post-coital tristesse]] (PCT) is a feeling of [[depression (mood)|melancholy]] and [[anxiety]] after sexual intercourse that lasts for up to two hours. [[Sexual headache]]s occur in the skull and neck during sexual activity, including [[masturbation]], arousal or orgasm.

In men, [[POIS|post orgasmic illness syndrome (POIS)]] causes severe [[myalgia|muscle pain]] throughout the body and other symptoms immediately following [[ejaculation]]. These symptoms last for up to a week.<ref name="Balon2005">{{cite book | title=Handbook of Sexual Dysfunction | publisher=Taylor & Francis |veditors=Balon R, Segraves RT | year=2005 | isbn=9780824758264}}</ref><ref name="Wylie2015">{{cite book | url=https://books.google.com/books?id=oH64CAAAQBAJ&q=Post-orgasmic+illness+syndrome&pg=PA75 | title=ABC of Sexual Health | publisher=John Wiley & Sons | year=2015 | pages=75 | isbn=9781118665565 | veditors = Wylie KR }}</ref><ref name="GARD">{{cite encyclopedia | title=Postorgasmic illness syndrome | encyclopedia=Genetic and Rare Diseases Information Center (GARD) | publisher=[[National Institutes of Health]] | access-date=30 July 2015 | year=2015 | url=https://rarediseases.info.nih.gov/gard/10809/postorgasmic-illness-syndrome/resources/1 | archive-date=5 March 2016 | archive-url=https://web.archive.org/web/20160305193016/https://rarediseases.info.nih.gov/gard/10809/postorgasmic-illness-syndrome/resources/1 | url-status=dead }}</ref> Some doctors speculate that the frequency of POIS "in the population may be greater than has been reported in the academic literature",<ref name="Ashby2010">{{cite journal | vauthors = Ashby J, Goldmeier D | title = Postorgasm illness syndrome--a spectrum of illnesses | journal = The Journal of Sexual Medicine | volume = 7 | issue = 5 | pages = 1976–1981 | date = May 2010 | pmid = 20214722 | doi = 10.1111/j.1743-6109.2010.01707.x }}</ref> and that many with POIS are undiagnosed.<ref name="McMahon2014">{{cite journal | url=https://www.statusplus.net/issm/saopaulo2014/presentations/082.pdf | title=Post-Orgasmic Illness Syndrome | author=McMahon CG | journal=16th World Meeting on Sexual Medicine | date=October 2014 | access-date=2015-08-24 | archive-date=2016-03-04 | archive-url=https://web.archive.org/web/20160304110554/https://www.statusplus.net/issm/saopaulo2014/presentations/082.pdf | url-status=dead }}</ref>

POIS may involve adrenergic symptoms: rapid breathing, [[paresthesia]], [[palpitations]], [[headache]]s, [[aphasia]], [[nausea]], itchy eyes, [[fever]], [[muscle pain]] and [[Muscle weakness|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. There is no known cure or treatment.<ref name="rarediseases.info.nih.gov" />

[[Dhat syndrome]] is another condition which occurs in men: it is a [[culture-bound syndrome]] which causes anxious and [[dysphoria|dysphoric]] mood after sex. It is distinct from the low-mood and concentration problems (acute aphasia) seen in POIS.
