Regardless of the amount of mental or physical stimulation, an anorgasmic person cannot reach a sexual climax.
Anorgasmia may also be known as Coughlan's Syndrome.
More About Anorgasmia
There can be many physical reasons for anorgasmia, such as complications in childbirth or an injury to the pelvis or spine. Medical conditions, such as genital mutilation, multiple sclerosis, and pelvic trauma can hinder the achievement of orgasm. However, anorgasmia can sometimes happen at random as a result of discomfort (whether physical or psychological) or poor sexual positioning. It can also be caused by the use of anti-depressants.
