Only by purchasing condoms correctly can you achieve the best contraceptive effect. Therefore, when we buy condoms, we need to pay attention to the types of condoms. From the surface processing of the condom body film, there are granular and threaded types. 1. There is no clear regulation on the product classification of condoms . Generally speaking, according to the nominal width of the condoms, they can be divided into three types: large, medium and small. Condoms with a nominal width of 55 mm are equivalent to the previously used specifications of Φ35 or large condoms. A condom with a nominal width of 52 mm is equivalent to a Φ33, or medium-sized condom. A condom with a nominal width of 49 mm is equivalent to a Φ31 or small condom. If a larger condom is used, it may easily slip out of the vagina, causing semen leakage and leading to contraceptive failure. If the condom is too small, not only will the maintenance of the erection be limited, but it will also easily cause the condom to break and lead to an unwanted pregnancy. Therefore, when purchasing condoms, you should choose products with a nominal width that suits you. 2. The shape of the condom is cylindrical , which can be divided into: A. Ordinary type (smooth or flat type): with a spermatic vesicle at the top and a smooth body; B. Expanded type with a tip; C. Constricted type: 1 to 4 strangled segments are made in the body of the condom From the perspective of surface processing of the condom body film, there are granular type and threaded type. Granules can be divided into large and small granules. The rib type is also called the ring type. This processed condom can more or less increase the stimulation to the vaginal wall and improve the quality of sexual life. The above two types of condoms are often referred to as special-shaped condoms. 3. Fragranced condoms. In our country, this is a type of condom with various flavors added, which was launched in the early 1990s. The types of added fragrances include rose fragrance, osmanthus fragrance, etc. 4. Medicated condoms . This is because condoms are added with nonoxynol spermicide, anti-inflammatory drugs, sexual excitement delaying agents, erection aids, etc., and are called double insurance type, drug type, and delayed type condoms, which are collectively referred to as drug-type condoms. 5. According to the different sealing packaging materials , condoms are divided into simple package and hardcover package. Simple condoms are packaged in plastic film, which has poor sealing and light-proof properties; hardcover condoms are packaged in double-sided or single-sided aluminum foil, which has ideal light-proof and sealing properties. 6. These are the types of condoms commonly seen on the market . Men should choose appropriate condoms according to their specific circumstances and preferences. |
