A climax delay spray is a type of topical solution applied to the penis to help men prolong their sexual performance by delaying ejaculation. It typically works by temporarily desensitizing the penis, reducing its sensitivity to sexual stimulation and thereby delaying climax. These sprays often contain anesthetic agents such as lidocaine or benzocaine, which numb the nerves in the penis to delay ejaculation. They are designed to be sprayed directly onto the penis shortly before intercourse and should be used according to the instructions provided by the manufacturer.
