Starting out.

Does initial penis size affect how the routine is created?

No.

Welcome to Thunder’s Robbic, :)

I imagine if one started out with a micro penis, jelqing would be a difficult chore. Therefore, the routine might be geared more toward “stretching” exercises until a more suitable length is achieved for jelqing. :)

Yes it can. If you are already long but thin, you might want to target girth. Conversely, if you are short and fat, you might want to target length. Things like that.

But just starting out, it is usually best to do the newbie routine to condition your penis to the process. Then after a few months, you can start specializing.

Welcome! I found that as my DrillBit grew, Jelqing became a lot easier. Try all the different things and see what works best for you - just remember to be methodical don’t ever quit. This exercise program is for life.

No, in the start it doesn’t matter how big you are since you have to start with the newbie routine.

When you are conditioned, then like gprent said, you can start focusing more on girth or length, whichever you want more.

Thanks for feedback guys. Really appreciated.
