Good evening, I would like to buy some delaying condoms because in the last period I happen to last really short in bed. I am afraid, however, that they hurt. I would like to know how delaying condoms work and what substances they contain, and if they are harmful to health. Thanks, Luciano Good evening Luciano. Retardant condoms contain an anesthetic, which has the purpose of "sleeping" slightly the penis, decreasing its sensitivity and thus prolonging the duration of the erection. Very often, in fact, the very fast achievement of ejaculation is due to a heightened sensitivity of the penis, especially in certain areas, such as the tip. A delaying condom, with its light content of benzocaine or lidocaine, anesthetizes the penis in a very mild form, allowing to postpone the moment of the climax of pleasure. If used occasionally, or continuously but only for short periods of time, delaying condoms are not dangerous to health and do not present contraindications. Our advice is to buy a pack, choosing from the most reliable brands that we have in our catalog, to see how you find. If you find them comfortable, use them in peace, but alternating their use with classic condoms, also in order to monitor your sexual performance without "help". If you should notice that the duration of your erection has decreased even further, it may be the cause to investigate more thoroughly the causes. Regards!
