You're 23? Go to thunders.org and learn about about stretching,
Hanging, pumping. You'll be able to gain length..perhaps an
Inch or more.
Girth is easier gain. This website has literally hundreds of threads devoted to it.
I am baffled that you have the threads pertaining to The Implant and still thinking about it. Every week or so I get a private message form some new recipient that needs to have it removed.
Think about this decision carefully.
