Can you tell me how could i make my penis head less sensitive?

Apply topical...: Using topical desensitizing cream 15-30 minutes before coitus will help. The ingredients of such creams are local anesthetic agents such as lidocaine, prilocaine, or benzocaine. The newest one, a topical aerosol, has faster effect so using it some 5 minutes before coitus. Of course, follow manufacturing instruction. For detail, ask doc timely.
