Do condoms have a size?

Condom is a cylindrical film sleeve made of high-quality natural latex, with a length of 19 cm, and a small capsule with a length of 3 cm at the distal end called seminal vesicle, which is the place where semen is stored during sexual intercourse. The proximal opening (cuff) has a slightly elastic rubber band, which can be put on the penis to tighten the penis. Condoms can be divided into four types according to the diameter of the opening: large, medium, small and extra small. The diameter of the opening is: large size 35 mm, medium size 33 mm, small size 3 1 mm and extra small size 29 mm

Condoms come in many colors, such as milky white, pink and purple. According to the thickness, there are ordinary, thin and ultra-thin types; According to the performance, there are dry and wet (condoms are coated with silicone oil to lubricate the vagina during sexual intercourse); Formally, there are small capsules on the front of condoms, and some condoms are flat on the front. The surface of most condoms is smooth, and a few condoms are gelatinous or ribbed, which can increase the sexiness of women during sexual intercourse.

In order to make condoms play a greater role in family planning, it is reported that Tianjin Latex Factory will gradually introduce a series of new products, such as delayed condoms that can prolong sexual intercourse and treat premature ejaculation, strengthened condoms that can help women with mild impotence and anti-inflammatory condoms that can treat women's diseases such as cervicitis.
