Coffee helps sexual intercourse, but men should drink less

　　Therefore, some people say that before sex, drink coffee Or tea, which can well regulate people's mental state. So, what effect does caffeine have on sex? Before answering this question, we must first explain what is the refreshing effect.

　　Simply put, this is because the caffeine in coffee or tea stimulates sympathetic nerve Caused by. The sympathetic nerve is in charge of all activities during the day. As long as it is stimulated, energy can be restored and everything will become more active.

　　But from another perspective, this matter is equivalent to suppressing the parasympathetic nerve. Since the sympathetic nerves and parasympathetic nerves have a superficial and inner relationship, when the sympathetic nerves are active, the parasympathetic nerves, which are weaker than the sympathetic nerves, are suppressed.

　　The parasympathetic nerve is responsible for night physiology, erection and other sex-related parts. If caffeine is taken in too much, it will have a negative effect on sex.

　　Therefore, instead of trying to use some widespread but useless reinforcement male It is better to truly understand the effective method here than the heroic method. Therefore, people who usually have high emotional ups and downs and whose sympathetic nerves are easily excited, especially before having sex, are best not to drink caffeinated coffee and other beverages. In order to avoid suppressing the parasympathetic nerves and reducing sexual desire.
