Topical drugs: It is recommended to apply local anesthetic on the glans penis under the guidance of a doctor, such as lidocaine cream, oxybutynin gel, dicaine and so on. Applying local anesthetic on the glans penis before sex can make the penis feel sluggish, delaying ejaculation and prolonging the time of coitus. 2. Oral medication: It is recommended that selective 5-hydroxytryptamine reuptake inhibitor drugs, such as sertraline, dapoxetine tablets, fluvoxamine, etc., be taken orally under the guidance of a doctor.
