Well, who don't want to have a longer enjoyment? The delay type condom usually provides the functionality by two principles: by physical property or by anesthetics. A thicker condom reduces sensitivities safely and effectively. However, for those who really cannot control the excitement may need extra help from anesthetics like benzocaine or lidocaine.
Due to poison control in Hong Kong, online sales of condoms with anesthetics has been banned since 2016.
