Most delay creams and male delay sprays use either lidocaine or benzocaine as the numbing agents. These are both anesthetics that are commonly used as topical numbing treatments in medicines and pain relief products. If you have ever been numbed at the dentist, it was likely one of these two products which did it! There are also natural options available which use plants to desensitize. The most common plant used for this is cloves but some will include other natural plants and herbs too. These are a great option if you are into all-natural products and they will generally be a bit kinder to your skin and have less risk of irritation or sensitivity to the chemical-based options.
