The intensity, duration and frequency of orgasms varies a great deal among women, as does the amount of stimulation required to have one.

Some women require stimulation beyond what would be considered normal, and others can’t achieve an orgasm at all. Difficulty in achieving orgasm is known as female orgasmic disorder. It’s also be referred to as female sexual dysfunction, orgasmic dysfunction and anorgasmia.

Female orgasmic disorder is a persistent problem and can cause women significant distress. It’s the second most common sexual disorder among women. It’s estimated that 15% to 18% of women in the United States, Europe, Central America and South America are affected by it. In Asia, rates range from 30% to 46%. Moreover, the condition becomes more common as women get older.
