I'm 19 and I have noticed the various signs of puberty but I didn't notice many of them until around 8th grade-9th grade but I'm wondering If my penis will grow any larger in girth, it grows every few months in length I think but I could be wrong. Only problem is that because I'm living at a relatives house I don't have a ruler and I don't have a printer to print out one of those printable rulers! Only thing I can think of is posting a picture which I hope I don't offend anyone with...
