Caffeine can help sex, but not everyone can drink it.
The study found that coffee has a refreshing effect because it contains caffeine. Of course, caffeine is not only found in coffee, but also in green tea, black tea and so on.
Therefore, some people say that a cup of coffee or tea before sex can well regulate a person's state of mind. So what effect does caffeine have on sex? Before you answer this question, you must first explain what is meant by the refreshing effect.
Simply put, this is because the caffeine in coffee or tea stimulates the sympathetic nerve. The sympathetic nerve is in charge of all the activities during the day. As long as you stimulate it, you can regain your energy and become more active.
But from another point of view, it is tantamount to the suppression of the parasympathetic nerve. Because the sympathetic nerve and parasympathetic nerve belong to the relationship between exterior and interior, when the sympathetic nerve is active, the parasympathetic nerve, which is weaker than the sympathetic nerve, is suppressed.
On the other hand, the physiology, erection and other sex-related parts of the parasympathetic nerve at night, if caffeine intake is excessive, will have a negative effect on sex.
Therefore, instead of using some widely spread but useless methods to strengthen masculinity, it is better to really understand the effective methods here. Therefore, the usual emotional ups and downs, sympathetic nerve easily excited people, especially before sex, it is best not to drink some caffeinated coffee and other drinks. So as not to suppress the parasympathetic nerve and reduce the libido.
