It is a common cause of unhappiness among many men to have what they perceive (and what may well be) an small sized penis head. Now, although this exercise should not replace any other in your routine (nor hinder it), needling can help to increase the size of your penis head. An important note to observe before starting this exercise though that this exercise has as its primary objective the aim to increase the size of your penis head when erect, and although flaccid gains may also be made, it is likely they will be much less significant than erect gains.
