**Health has always been a top concern for men. Here are five physiological points about * * safety, which you should know:
Physiological point 1: Many people have a slight curvature during an erection, and the degree varies from person to person. Some may bend upwards or downwards, while others may lean to the left or right. This is definitely not a special ability or strange disease, but it is already normal without causing discomfort or hindering your sexual activity.
Physiological point 2: What standards do men usually use to measure their masculinity? Muscle, strength, or length of * *? In fact, Eastern people have similar erections, which are about 10 to 15 centimeters after erection. In fact, sexual ability is not related to the length of * *. The so-called "short and refined rod" may seem very majestic, but it turns out to be not suitable for use. Therefore, it is important to remember "not to show off the shortcomings of a Taoist, not to show off one's own strengths".
Physiological point 3: The time required for sperm production is approximately 90 to 116 days, and it can survive in * * or the cervix for 72 hours.
Physiological point 4: * * is mostly caused by the corpus cavernosum, which is covered by a layer of epidermis. When sexual excitement occurs, the corpus cavernosum becomes congested, causing * * to become hard, longer, and thicker for * * use, which is called "erection".
Physiological point 5: For some men, being able to maintain an erection for a longer period of time can be their dream goal. Some people also compare the length of time they hold it up, but staying up for too long can actually be frustrating. Because having an erection for too long without dissipating can not only prevent you from enjoying the pleasure of sexual desire, but also make you feel extremely painful. Injecting drugs to treat impotence or developing leukemia can cause this situation.
