Sexual dysfunctions are quite common in general public.
For example, premature ejaculation is seen in every 3-4 men, anorgasmia (no orgasm, no sexual pleasure) is seen in every 3 women, vaginismus (painful sexual intercourse or having no sexual intercourse due to severe pain) is seen in about every 10-12 women.
Masters and Johnson defined the sexual response to physiological stimuli in humans in 4 stages:
Sexual dysfunctions are caused by failure in sexual response stages.
Acupuncture is effective in all sexual dysfunctions. Acupuncture with traditional and complementary medicine will also increase the success rate.
