The main method of using premature ejaculation sprays is to spray the sprays on the glans, the tether, the coronal groove and the foreskin about half an hour before intercourse to reduce the sensitivity of the glans by the action of the medication. These sprays are washed off 3-5 minutes prior to intercourse, and then intercourse takes place. The most common sprays available today, are lidocaine aerosol or ointment. After sexual intercourse, these sprays have no effect on the woman’s vagina or the man’s penis, either. If you have premature ejaculation, you can use the sprays for treatment, which can be used to improve the duration of intercourse.
