A sexual life should not be over 15 minutes Time has nothing to do with the sense of achievement
At couple pass sexual life, from both sides being excited to begin to ejaculate, expire, under the normal situation, about 5-15 minute such as duration, certainly, each physical condition of couple, sex habits and customs,etc. different, even if is the same as a couple, it is different to pass detailed conditions and environmental condition of the sexual life,etc. each time, so, the duration of each sexual life is really long and suitable much, it is very difficult to make a standard.
Someone thinks it spends the the longer duration of sexual life each time and can obtain the relief, these kind of view not science, the physiological research of the sex shows, the time of the sexual life of once is sustained very long, it is unfavorable to the health of both sides.
First, while passing the sexual life, not merely the men and women organ is in high congestion state, and from the sex excitement one to climax one, a lot of histoorgans of the human body have participated in this special physiological course, for example, the in short degree of whole body muscle is obviously strengthened, the heartbeat is accelerated, the cardiac muscle shrinks and strengthens, blood pressure rises, breathe and strengthen accelerating, the skin blood vessel of whole body is expanded, the perspiration increases, wait a moment, therefore the energy consumption of the organism obviously increases, the supersession is strengthened, if the time to pass the sexual life drags very long, will make the intersection of energy consumption and I of human body and make people feel weariness, make both sides appear spirit to be languid, the acid of muscle is carried, it is uncomfortable that whole body is weak,etc., the work or physical labor that certainly will influence the next day in this way.
Second, while passing the sexual life, the men and women organ keeps in close touch and the activity in high congestion state, if time is too long, initiate various diseases easily, prove clinically, the duration of sexual life is too long, women are apter to cause secreting the urine to be infected with, period is disorderly,etc., men initiate prostatitis,etc. easily.
Point out: Must pay attention to cleaning while passing the sexual life
End in front of the sexual love it prepares to be hygiene before the sexual intercourse, some people dislike trouble, unwilling to fulfil the hygiene work before sexual intercourse, this is not appropriate. Men and women must brush teeth, because breathe out the bad smell in the mouth, become unpleasant to kiss to not merely make, and will probably make the other side give up the hope of sexual intercourse.
No matter men and women should keep the cleaning of the genitals, especially among sexual intercourse, should pay attention to the hygiene question even more.
The penis is a male mating organ, must wash before sexual intercourse. Prevent bringing the bacterium into women's vagina, make women suffer from gynaopathy. Often accumulate some dirt between foreskin and glans penis of the penis, the dirt must be washed, and should turn over and clean the inner cover.
Women's vulva has a lot of fold, sweat gland, sebaceous gland and vagina to secrete and often accumulate and store in the fold, and the vagina locates between urethra and rectum, it is very easy to be infect. Must wash genitals before sexual intercourse, otherwise easy to make germ enter vagina and infect in sexual intercourse.
