Contraceptive long-lasting condoms refer to condoms that are long-lasting and are generally not harmful to men. However, if you are allergic to the condom material or benzocaine, you may experience symptoms such as itching and rash. The main purpose of condoms is to prevent pregnancy, and they are physical contraceptives. Durable condoms, compared to ordinary condoms, mainly contain benzocaine, which is a local anesthetic that can reduce the sensitivity of the penis head and delay the ejaculation latency time. Generally speaking, durable condoms are not harmful to men, and the components of the drug contained therein are within the range of the human body’s ability to tolerate. However, if one is allergic to benzocaine or the natural latex components in condoms, it may cause symptoms of allergic reactions such as itching, rash, burning, pain, etc., which are harmful to men if not treated in time. In daily life, it is necessary to use condoms in a reasonable and standardized way and take correct contraceptive measures.
