Do worry that you might be smaller than the average erect penis size
? In order to understand penis size it's important to know how to measure it correctly you'll be amazed at how many people measure themselves the wrong way. The penis needs to be fully erect in order to have any true representation of actual size - hold a ruler to the base of the penis pressing against the abdomen then measure to the very tip of the penis. You might be surprised with the results and find you're actually within the average erect penis size bracket.
