1, obsessed with pornography Sexologists have recently found that the more men watch erotic films, the more they will worry about their sexual skills, and this pressure will image their play in bed. Men are accustomed to accepting erotic films conveyed by the “sexual knowledge”, like to edit the new sex patterns, the pursuit of visual stimulation. In this way, it is no longer easy to achieve orgasm in reality, and may even develop erectile dysfunction. Studies show that too much exposure to erotic content can consume a man’s desire to neglect normal sex with his significant other. The men who often watch erotic images will be overly dependent on masturbation, and over time may not be interested in normal sex. 2, drink too much dairy products A study found that if the daily overdose of dairy products, it will cause a decrease in libido. The most common drink in our lives is milk, and its benefits are numerous, but if you drink dairy products in excessive doses every day, it can cause a decrease in libido. Medical experts explain that any food contains molecular antigens that can cause allergies. If a person consumes milk, wheat, eggs, soybeans, tomatoes, fermented products and chemical additives in a single serving all year round, they are all prone to the formation of allergy molecules. When the body takes food, the antigens stimulate the immune system and produce antibodies. With a proper diet, the body’s own “housekeeping” system can sweep them away. And long-term taking a single food, the body of this sweeping function will be covered up, antibodies will be like a snowball rolling bigger and bigger, it may stay anywhere in the body, blocking microvascular, obstructing the popularity of blood, resulting in reduced sexual function. 3, dinner eat too full romantic dinner is easy to unconsciously eat too much, but reduce the libido, which in turn affects the normal sexual life. Experts say that after eating, gastrointestinal digestion, absorption of food needs energy, so the supply of blood in the gastrointestinal increased, while the supply of blood to other parts of the body will be reduced accordingly, which will affect the male erection and the ability to feel sex normally. In addition, if you drink a lot of alcohol during the meal, most women and some men will experience a decrease in libido, which is also not conducive to sexual life. Therefore, it is recommended that it is best to enjoy the pleasure of fish and water with your partner about 1 and a half hours after the meal. 4, taking sleeping pills Insomnia is an urban white-collar “epidemic”, when you can’t sleep, eat a few hypnotic pills, become people deal with insomnia routine, but sedative-hypnotic drugs will have an impact on the level of human sex hormone secretion, if long-term use of such drugs, may cause abnormal secretion of sex hormones, resulting in sexual dysfunction and even disorders. Some components of sedative-hypnotic drugs, such as phenobarbital and scombobarbital, can easily become addictive if taken in large doses over a long period of time, so that the brain’s ability to discriminate sexually and the release of pituitary gonadotropin is inhibited, making people lose their libido and orgasm. In addition, androgenic drugs, such as methyltestosterone and testosterone propionate, can cause testicular atrophy and reduce sperm and semen if taken in large quantities over a long period of time. And estrogens, such as estradiol and ethinyl estradiol, if used to treat prostate cancer, may inhibit the production of testosterone, causing a rapid decrease or loss of libido and leading to impotence and impaired ejaculatory function. However, although these drugs can reduce sexual function, the symptoms usually improve or disappear on their own after 3 to 6 months of discontinuing the drug.
