The top of a "long-lasting" condom has a small amount of lubricant that evaporates under the action of body temperature. These lubricants contain benzocaine, a mild anesthetic that can reduce the sensitivity of the head of the penis, thereby prolonging sex.

As far as sexual pleasure is concerned, both men and women want to extend the enjoyment time, but they must also understand and prevent possible side effects. Topical anesthetics can cause allergic reactions in some people, causing local redness, swelling and itching, and in severe cases, shock. At the same time, long-term use of topical anesthetics will cause sequelae of nerve conduction disorders and local sensory abnormalities. Therefore, long-term use of condoms with added topical anesthetics may cause the above-mentioned complications. You should be more careful especially when there are wounds on the skin. Therefore, when choosing the type of condom, you must first understand your own needs. If you can first seek the opinions of your sexual partner, you can show more mature mutual respect and make sex more satisfying.

If you really want to extend the time, you can choose to wear two condoms, and these three methods are most effective:

1. After putting on the first one, wrap a circle of toilet paper around the glans, and then put on the second one;

2. After putting on the first one, cut off the glans part (don’t hurt the penis), and then put on the second one;

3. Cut off the condom part of the first condom, leaving only the rubber ring, put it in the turtle groove, and then put the second condom on.

10 details to pay attention to when using condoms

1. Check the production date and expiry date before use. Expired condoms have deteriorated and are easy to break and should not be used.

2. Condoms must be stored in a cool, dry environment and away from acids, alkalis, and oils. If it becomes sticky or brittle after exposure to the above conditions, it should not be used even within the shelf life.

3. Condoms have different specifications. The appropriate model should be selected according to the size of the penis when it is erect. Otherwise, it will be too tight and easy to break, and too loose and easy to slip off, which will affect the effectiveness of use.

4. The condom should not be unfolded in advance, but should be unfolded on the head of the erect penis downward from the glans.

5. Before putting on the glans, you should pinch the small air bag at the top of the condom for storing semen to prevent the air in the air bag from expanding when heated, causing the semen to overflow to the root of the penis during ejaculation.

6. Condoms should only use water-based lubricants. Vaseline, liquid paraffin, facial oil, cooking oil, etc. can increase the brittleness of condoms in a short period of time and accelerate their rupture.

7. If a condom is found to have holes or slip during use, it is still unsafe to just replace the condom. Sexual intercourse should be stopped immediately and the genitals should be cleaned with disinfectant.

8. After ejaculation, press the bottom of the condom with your fingers and pull it out together with the penis before the penis becomes weak.

9. When removing the condom, do not allow semen to flow out, and do not allow vaginal secretions outside the condom to come into contact with the body. Each condom can only be used once and used condoms should be placed in a plastic bag and thrown into the trash.

10. It is impossible for the fingers to take off the condom without coming into contact with semen and vaginal secretions at the same time, so you must wash your hands immediately with soapy water under running water.
