For temporary relief of premature or over rapid ejaculation, Stud 100 has the only male genital desensitizer formula with lidocaine. Spray the head and shaft of the penis with the pre-measured pump at least five minutes before active stimulation. Lidocaine will be absorbed by the skin leaving some slight desensitization for better ejaculatory control. Once absorbed, Stud 100 has no taste, no odor and will not rub off. 120 premeasured sprays per bottle.
