Hanging

Is hanging really necessary? I want to be longer, but I don’t want or have the time to hang. What does hanging actually do besides pull?

No, hanging is not necessary. Some guys gain just fine without it, others don’t. What hanging does is to create micro tears in the ligaments that attach the penis to the body and then it heals in the longer state.

You might want to consider an ADS, or just stretch and jelq, its up to you.

I have been PEing for two years, I never hang anyway. I gained a lot from just stretching.
You should start with manual stretch, the basic length exercise, then go for V-Stretch, JAI Stretch etc.

Good luck!
