Glans sensitivity can be improved with anesthetic medications, such as topical medications like lidocaine gel and dacronine ointment. Sensitive glans can be reduced by applying local anesthetic drugs to reduce the sensitivity of the glans, such as lidocaine gel and dacronine ointment. It can achieve the effect of delaying ejaculation. Usually used when about 20 minutes before sexual intercourse, the drug will be applied to the glans or its sensitive area, feel the effect and then wash off before sexual intercourse, so as not to spread the anesthetic to the vaginal wall, resulting in the partner feeling numb. Patients with sensitive glans should go to the hospital to use the drug under the guidance of a professional doctor as prescribed by the doctor, do not use the drug privately, so as not to cause discomfort.
