Be the king with Sta-Hard Super Spray! Sta-Hard is an effective way to reduce over sensitivity and help the user last longer. Spritz 1-2 sprays onto the penis before intercourse to mildly numb the glans, then allow a few minutes for the product to absorb and take effect. The penis should be lightly desensitized but still able to maintain an erection. The usher may apply additional sprays as needed.
