Each has an adjustable Secondary Body that covers the cockhead (glans of the penis) and lays over the urethral opening for centralized coverage; or may be focused elsewhere on the glans.
The Primary Body encircles and stimulates just beneath the coronal ridge area. The Primary and Secondary Body of each Electrode intersects and lays at a strategic point, the frenem, allowing the stimuli to cover the entire external area of the cockhead.
IMPORTANT: To find your proper fit, measure the circumference of the cockhead while erect. To find your inner diameter, divide the circumference of the cockhead by 3.14. They are available in three inner diameters: 1", 1 ¼", and 1 ½". Keep in mind that the erection may not always be fully hard, so choose what diameter will work best for you in both a fully erect & a softened state.
The adjustable Secondary Body of the Corona with Amplifier covers the cockhead (glans of the penis) and separates into a third body, the Urethral Amplifier (.125" in diameter and 1.60" in length). The junction at the Urethral Amplifier on the Secondary Body is easily adjustable, allowing the user to configure it to fit their urethral opening. This allows for proper anatomical placement for the overall effect of focusing the Electrode. The Amplifier extends only a short way down the urethral cavity to ensure heightened concentration of EES.
P.E.S. has found the Corona Stimulators to be of great importance in the quest for 'hands-free orgasm'. Some recommended product combinations to assist in this are configurations that incorporate stimulation to the head of the penile shaft via the Corona Stimulator in circuit with an item at the base of the penile shaft, such as the P.E.S. Tubular Mid-Ring or the P.E.S. Testicle Tubular around the scrotum.
You might find that a different configuration works better for you. Be patient and use your imagination. You will soon find the same pleasure that others find with EES.Like all P.E.S. Electrodes, the Corona "Cockhead" Stimulators require the P.E.S. Power Box in order to function, and are open to extensive experimentation with regards to how you wish to configure them. P.E.S. Low Profile Leads or P.E.S. Pin Wire to Low Profile Pinch Adapters are sold separately if you already have power source.
Please note that the single pole Corona "Cockhead" Stimulators require a second Electrode in order to function.
