Is there any truth behind the concept of a man being a grower or a "shower."
Do some men grow, while others remain the same size when aroused? It might seem like an urban myth, but Dr. Gonzalez says there is "some validity" to the idea. He notes some men have "larger appearing members when flaccid and there are others who gain length when aroused. He notes whether you grow or show, it does not affect someone's sexual health.
Dr. Gonzalez also tells The Doctors he is often asked about the average time it takes to achieve ejaculation and it's actually shorter than most people suspect -- at only 5 minutes.
And on the subject of "blue balls," which some debate whether it is real or not, the urologist explains that epididymal hypertension occurs when there is an increase in blood flow to the testes and penis, which occurs during arousal. Under typical circumstances following ejaculation, the blood will leave the genital area. He notes if there is no ejaculation, the blood can remain in the area and cause pain for some. Despite the idea that ejaculation is needed to relieve the issue, the urologist says it can actually make the issue worse.
