I am a white 21 yr old male who is 6'4 broad shoulders and love to work out. I also have a 9 inch penis (23 cm) never had a complaint about my size but I am giving DLD exercise routines a shot I want to see just how big I can get based off that I am already very well endowed. I am not lying about my size either I will post a link to video of me showing my size on a amateur adult web site. How big DLD do you think I could get or anyone for that matter that wants to make a honest comment. I also am looking to get into the adult film industry if anyone has any info.
