Are there different sizes for condoms?

Condoms come in different sizes, categorized as extra-large, large, medium, small, and extra-small, with a length of 19±1.1cm. Besides size variations, they are also classified based on thickness into thick-walled, thin, and ultra-thin types. The shapes include regular, cylindrical, concave-convex with several narrow segments, and special ones with uniform latex particles or ribs.

Some condoms also have a special scent containing both traditional Chinese and Western medicine ingredients. They are designed to be dry and may be lubricated with silicone oil or water-soluble lubricants.

1. Large: 55mm in width and 35mm in diameter.

2. Medium: 52mm in width and 33mm in diameter.

3. Small: 49mm in width and 31mm in diameter.

4. Extra-small: 48mm in width and 29mm in diameter.

5. Condom thickness can also be classified as Type A: 0.36mm; Type B: 0.28mm; Type C: 0.20mm; and Type D: 0.12mm. Regular thickness ranges from 0.04mm to 0.06mm, ultra-thin is 0.03mm, and thin is between these two ranges.

1. Choose a condom of the appropriate size based on the erection size. If it is too large, it may easily slip off. If it is too tight, it may cause discomfort.

2. Do not store condoms near pockets or other heat sources. Prolonged exposure to heat can cause rubber to degrade. Avoid using expired condoms, as they are more likely to tear.

3. Before use, blow air into the condom, pinch the opening, and check for leaks. Release the air before use.
