How long can durable condoms be delayed? How long does the extended condom take effect
Can durable condoms really be delayed?
There is a small amount of lubricant on the top of a long-lasting condom, which can evaporate under the action of body temperature. These lubricants contain Benzocaine, a mild anesthetic that can reduce the sensitivity of the penis head and thus extend the duration of sex. One type is thickening (mostly just thickening the front end), which is more expensive. One is to add medication to the condom to delay male ejaculation time.
Different manufacturers use different drugs and useful natural plant extracts. Also using benzocaine (anesthetic) and condoms with anesthetic additives can cause male penis inflammation, which is no longer used by large factories.
2. The History of Condoms
Condom condom, whose history can be traced back to thousands of years ago in Ancient Egypt, is said that the penis condom appeared more than 2000 years ago in Ancient Egypt, but at that time it was a symbol of wealth and status, hanging on the clothes as accessories. Around 1000 BC., The ancient Egyptians began to use linen jackets to prevent disease.

However, there has been controversy among various historians and archaeologists regarding the use of condoms in the 1st to 2nd centuries AD. Nevertheless, the murals with condom patterns were found on the murals in the Cambarez cave in southern Southern France, which strongly proves that condoms originated in Europe. In addition, during the ancient Roman Empire, some evidence of condoms was also discovered.
Later, the ancient Roman Empire gradually declined in the 5th century, and contraceptives were no longer used in Europe. People's understanding and use of condoms disappeared with the downfall of the ancient Roman Empire. From the downfall of the ancient Roman Empire to the Renaissance, due to the long-term high-pressure rule of medieval Christianity, doctrines such as abstinence and original sin almost lost the culture of contraception.
3. The production process of condoms
Compounds mainly refer to the process of producing raw materials used in the production of condoms. Adding various raw materials to natural latex increases its elasticity and prevents its aging., It needs to be reacted in a temperature controlled container, and the raw material of the condom will eventually form., During the synthesis process, it is also necessary to constantly monitor and conduct sampling inspections to ensure the quality of the raw material solution.
After the raw material solution is prepared, the process of forming the condom can begin. Place the hard glass mold into a qualified raw material solution, then slowly stretch the raw material solution to evenly lay it on the surface of the mold. After the raw material solution on the mold is dried, it is soaked again to fill the gaps., Form a thin and uniform rubber film on the surface of the mold, then slightly roll up the edges to form the shape of the condom. The shape of a condom depends on the shape of the mold. The surface of the mold has textures or bumps, which can be used to produce other types of condoms, such as threaded or raised condoms.
