Correct sex life knowledge, boys must see
MThe semen ejaculated by men is mainly composed of seminal plasma and spermatozoa. Seminal plasma contains various proteins, enzymes, and inorganic and organic salts. The discharge volume of male intercourse is generally 2 to 6 ml, of which 90% is seminal plasma. If a man has more than one night, excretion will be significantly reduced, which is a self-protection mechanism.
How often do you have sex?
The frequency of sexual intercourse must not be too high, and the most suitable frequency of sexual intercourse must be formulated according to your specific situation. If the sex life is too frequent, the men's waist will suffer from lumbar muscle strain or cause some other waist diseases. After all, men are in the dominant position in sex life.
Your intercourse posture?
It is understandable to pursue some new postures yourself, but you must pay attention to your safety. Although some poses are stimulating, they are not suitable for long-term use. The muscles themselves are in a state of tension. If the posture is wrong, it is easy to damage the joints, strain the muscles, and cause low back pain.
Was your intercourse interrupted?
When some people are having sex, they are suddenly disturbed by external factors and have to stop having sex. At this time, it is easy for men to have low back pain. In the process of sexual life, the brain is too excited, and the seminal vesicles and other accessory organs are not completely emptied. The sudden interruption will make men feel lower back pain.
Sex multiple times in one night?
Under normal circumstances, one-time intercourse a night is a very suitable number of times. If you have sex two or more times a night, a man's prostate will always be in a state of congestion and swelling, and the nerves in the waist will be stimulated, which will lead to lower back pain.
Prostatitis is a prevalent disease in men, which is also the cause of low back pain in men after sexual intercourse. During sexual intercourse, the male prostate is congested and swelling.
Stimulated by inflammation, men will feel back pain. If, after sexual intercourse, the back pain is very long and difficult to relieve, you should go to the hospital to see if it is caused by diseases such as prostatitis.
