Herbs # There are two things that make a penis small: the inability to have a full erection and the actual length of the penis. Most of the herbal medicines sold on the market help in improving the quality of the erection. When the penis achieves full erection, it is largest and thickest. When men who are not able to achieve this full erection take these pills, they find that their penis does indeed "grow." Actually, the increase in size is due to the herb's ability of pushing the penis to grow the hardest and largest erection. One great plus point here is that such pills seldom have any negative side effects. Vacuum Penis Pumps # This works on the same principle: get the greatest amount of blood into the penis so the man gets the biggest and hardest erection. In other words, the penis is stretched at the most due to the flood of blood into it. The increased growth in length and width is mainly because now the erection is at its best. Beware that some vacuum pumps may result in nerve damage and even impotence, if these are overused Exercises # This, in combination with pills that promote optimal flow of blood into the penis when excited, can actually help in achieving extra growth. The penis, being a muscle, responds well to exercises--something very similar as building your biceps with exercises. When these exercises are combined with pills that improve the quality of erection, there may be a visible difference in both length and width of the penis. Herbal Ointments # This is yet another way to manipulate the function of the penis to stretch. Herbal ointments usually contain the same ingredients that pills have, and help the penis achieve and sustain a full erection. The ointment's role is often to numb the nerves in the head of the penis so as to allow it to build a sufficiently strong erection that can be maintained long enough to satisfy your partner; plus the numbness will help you prevent premature ejaculation. Conclusion # As you can see, penis enlargement is normally achieved by promoting and sustaining the maximum possible erection of the penis. In some tribes in Africa, the penis is enlarged by tying weights to it for years until they are satisfied with the length. However, this process is dangerous as it stretches and actually weakens the muscles of the penis.
