Netizen asked: “My partner is 50 years old, amenorrhea, but the most now in sex vaginal dryness, the desire to have sex but a dryness also stopped, is there any medicine, because the cooperation is not good I most now also premature ejaculation, sometimes on two or three minutes to ejaculate, I am 51 years old. I am 51 years old. Do I need medication? We used to have a very harmonious sex life.” Vaginal lubrication is an important physiological manifestation at the beginning of sexual intercourse. Inadequate vaginal lubrication is medically known as sexual arousal disorder, which is the male equivalent of impotence. The difference is that when arousal disorders occur in men, they are unable to complete their sexual life, while in women, arousal disorders can still continue, but they are a potential risk factor for women’s health, leading to infections and inducing a variety of diseases. The national figure for female arousal disorders is 74.8%, but only 7% of people with the problem choose to seek medical attention, most of them choose to seek solutions on the Internet or read books, which may delay the treatment of certain important problems. In contrast to male sexual arousal disorders, the percentage of people seeking treatment is very low. Experts analyze female sexual arousal disorders, most of which are mild and most of which are not pathological. 39.2% are due to bad moods or stress, 13.3% are due to condom use, and other common causes include postpartum and menopause, when estrogen levels drop, which can lead to vaginal dryness. For most non-pathological vaginal dryness, the use of human lubricants is recommended, with more than 67% of couples in the United States using lubricants.
