With the accelerated pace of social operation, the increase in work pressure, our life “night people” more and more, this group of people often seven or eight o’clock in the evening to get off work, home to eat dinner is also almost ten o’clock, in order to sleep and rest as soon as possible, many couples after dinner to seize the time to make out some, such a life once or twice occasionally nothing The life of the occasional one or two is not different feeling, but after a long time many people will feel uncomfortable, the sexual life between the couple is not as perfect as before, especially many male friends are not as hard as before. Why is this? We all know that you can’t do strenuous exercise immediately after a meal, because this will affect the digestive function, the reason is that after a full meal the workload of the gastrointestinal tract suddenly increased, the body will mobilize more blood to the gastrointestinal tract to participate in the work in order to help digestion. The same at this time the blood allocated in the reproductive organs should be relatively reduced, and the biggest feature of the sexual organs during sex is to be extensively engorged, if a full meal immediately after sex, then the body’s blood supply distribution will be a problem, the male erection hardness is not enough, so the sex life of both men and women are certainly not satisfied, at the same time in the penis is not firm or even some weak state forced to have sex will cause penile vascular The endothelial cell damage, in the long run men will appear erectile dysfunction. The traditional medicine of China has long warned people “have been full do not room, have room do not full”. For modern society, “night people”, the time of sex will be moved to dawn, may be a good choice.
