"How is erectile rigidity calculated as normal?"

The firmness of erection that is similar to the firmness of cucumber is considered normal. The firmness of male penis is divided into four grades. The first grade is comparable to tofu, the second grade is a peeled banana, the third grade is an unpeeled banana, and the fourth grade is cucumber. This is the normal firmness of male penis. You can compare with these grades to see if you are normal.

1. From a doctor's perspective, the firmness of erection can be divided into four grades. The first grade is having a little reaction after stimulation, but not firm; the second grade is having a reaction, but cannot be inserted; the third grade is able to insert into the vagina, but feels like a softener, easily falling over with a touch; the fourth grade is the best firmness, able to bring the best feeling to the other party after insertion.

2. The difference in erection firmness grades indicates different degrees of erectile dysfunction. The third grade firmness belongs to mild ED, while the first and second grades belong to moderate to severe ED. In addition, poor erection may also be an early sign of certain physical diseases, such as hypertension, heart disease, and diabetes, which can cause sexual dysfunction and damage blood vessels. Since the penis is mainly composed of blood vessels, this damage is first manifested in sexual dysfunction.

3. On average, young adolescents have an erection of around 6 times per night, each lasting 20-30 minutes; young adults have an average of 4 erections per night; healthy elderly people over 65 years old can still have a total erection time of 1 to 1.5 hours per night. Even children often have penis erections in their sleep.
