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:

1-Stimulation phase 
2-Plateau stage 
3-Orgasm stage 
4-Thawing stage.

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.
