No need for viagra (sildenafil): There is no universal answer and the timing varies among different people. The intensity of stimulation will determine the time before ejaculation. You apparently do not need viagra (sildenafil) as you do not have difficulty having an erection. Viagra (sildenafil) will not delay ejaculation. Viagra (sildenafil) does have side effects and rarely serious ones.
