Question to fwrak :
Why do you still want to increase your girth ? What your doing is like bodybuilding : increasing muscle mass for the sake of it. With no consideration whatsoever for aesthetics, practicality, or performance (yes sir, bodybuilders usually suck ass in terms of athletic performance). No offense to bodybuilders out there.
Your dick will be 7" + in girth ? fine. But you better get ready for a life time of misery with a big useless tool hanging between your legs. You will have a LOT of trouble finding a girl with whim you can have proper sex, and forget about oral / anal.
Dude, with all due respect, take a good look at your objectives and motivation, because you might be heading towards disaster with your current state of mind.
Perhaps you have certain issues that lead to you putting ALL your virility in your cock area. So of course you want to make it bigger than big. But your cock is not what makes a man of you. I am no shrink, but that's what a shrink would say.
And lastly, keep in mind that you were gifted with a one in ten thousands cock. Don't ruin it !
