The size of condoms is relatively fixed. An ordinary condom is about 19 cm long, and there is a sperm storage vesicle about 2 cm long on the top of the condom. There is a slightly elastic rubber ring at the proximal opening (cuff), which mainly serves to fix the genitals.

It depends on the condom size, model and specification. Generally speaking, the specifications of condoms can be divided into four types according to the diameter of the opening: large, medium, small and extra small. The one with an opening diameter of 35 mm is the large size (circumference is about 110 mm, the width is 55 mm), and the 33 mm diameter is the medium size (the circumference is about 104 mm, the width is 52 mm) ), 31 mm is a small size (width is 49 mm), and 29 mm is an extra small size.

Many condom models in China are medium-sized, and the width written on the package is "52 plus or minus two mm" (half the circumference of the condom opening). If you don’t know how to choose a condom model, you can measure your penis first and use the erect value as the standard.

Introduction to how to use male condoms

Male condoms are commonly used, but for men who are trying to have sex for the first time, they still need to use male condoms. Let’s take a look at how to use male condoms:

1. Take out the condom before sexual intercourse, tear open the package and carefully take out the condom;

2. Check whether the curled part at the end of the condom is outside. If not, it means it is worn backwards. When wearing a condom, you must squeeze out the air in the first section of the seminal vesicle;

3. Then slowly stretch the condom to the end of the penis;

4. After ejaculation, while the penis is still erect, you should immediately and firmly hold the condom from the base of the penis with your hands, and pull out the penis from the vagina as soon as possible. After the penis is completely withdrawn, take off the condom. Wrap it in paper towels and put it in the trash can.

Demonstration on how to use the female condom

1. Hold the inner ring with your thumb and middle finger, and hold the bottom of the sleeve with your index finger;

2. Choose a comfortable way, either lying down or sitting, hold the inner ring tightly, and put the condom into the vagina, the deeper the better, until you feel the correct position;

3. Repeatedly confirm that the condom is in the correct position and the main body is not twisted, and the open ring is always placed at the outer end of the vaginal opening;

Four. Men can slowly enter into sex (if there is no partner, put a dildo or g-spot massager into the body);

5. Take it out. To avoid semen flowing back, take out the condom before getting up. When taking it out, pinch and rotate the open ring, and then slowly pull the condom out of the vagina.
