When I was 12-15 I was also 7 inches, and about 5.5 round. It seems though after I turned 20 for whatever reason, I was a little over 8 all of a sudden this is when I felt hormones kicking in again and I was addicted to sexual stuff, and now these past few weeks I noticed my cock got alot heavier and thicker, I hhave no idea why, I started this medication called effexor which has no side effect such as this, but maybe its late stage growth. But these past few weeks i would wake up with a heavier cock, I went from 1.7 width, to 2 inch width in the last few weeks and Im not making this up, check my gallery, and slightly over 6 inch around as well. Its weird at this point of my life waking up and noticing my penis is heavier thicker.
