According to "Ruili" magazine, a famous American sexual medicine expert pointed out that coffee has a certain impact on sex. An appropriate amount is beneficial, but an overdose is harmful. Experts say that coffee affects sex because it has a direct impact on the sympathetic and parasympathetic nerves. The sympathetic nerves and parasympathetic nerves control each other in the human brain: during the day, under the stimulation of the external environment, the sympathetic nerves are dominant, making people excited; when sleeping at night, the parasympathetic nerves are dominant, making people relaxed.

If you drink more than two cups of coffee before sex, the sympathetic nerve will be over-excited, and people will not be able to have a relaxed and happy state of mind. The good emotions of sex will be replaced by anxiety, sexual desire will be reduced, and the quality of sex life will be reduced. It will be a big discount. If you drink more than two cups of coffee after sex, your body will still be in a state of excitement, which is not conducive to body recovery.

However, for people whose sympathetic nerves are not easily excited, or who have no sexual desire due to physical fatigue, drinking a cup of coffee before sex can arouse their emotions and increase the body's sensitivity to external stimuli. , was particularly impressed by the pleasure produced by sexual life. There are also studies showing that drinking a cup of coffee before sex can make orgasm occur earlier, and the effect on women is more obvious than on men.
