How big is a 13 year olds penis? -
13 year olds only
since at 13 some guys haven-t gone through puberty, but some are/have gone though it, so the size can change greatly
13 year olds only
a red neck way is to tie a five foot piece of brick twine firmly around penis tie the other end of twine around a 12 in concrete block drop off a five foot ledge it will only hurt a little if it is still not big enough try a higher ledge
