Dear doctor, whenever I see the others long penis then every time I think about that and think about the increasing the length of my penis. Please help me by giving the suggestion about the tips for long and strong penis

Long and strong penis is men’s obsession. There is no medicine or measure on this earth for increasing size of penis. Like height and weight, size of penis is also not same. Strength of erection depends upon many factors like desire, external stimulation, fantasies etc. You should not take any medicine to increase it unless you suffer from Erectile Dysfunction.
