Not wearing underware.

I wear a 1/2" heavy PA all the time and it has stretched my cock. I only go commando (freeball). I have some boxers and griefs with huge a pocket for my equipment but it is to restrictive for me. I love the feeling of my PA swing as I walk.
 
My husband has been going without underwear for years... he loves the feeling and I do too. He is not huge... but I do like the feeling of rubbing his bare ass or groping a feel every now and again.

He also says he likes the feeling and finds underwear very constricting. Before, he wore briefs... didn't like the boxers. Now, just think of all the money we save with both of us going commando 99% of the time. :smile:
 
I trust that you are measuring your package to ascertain what is really happening. I would suggest that you measure after a relaxing warm shower so that you can determine if the growth is real or just a state of excitement. Be consistent and you will soon determine if the freeballing is improving your length.
