I don’t think there needs to be a separate forum. But Jelqbeginner’s point that things need to be done differently for a small penis are correct.
This is the first time I’ve been inspired to post. I started 3 years ago with a very, very small penis. 2 inches or less flaccid and 3.5 inches erect. Now I am 3.5 flaccid and almost 6 inches erect.
Specifically, you have to grip from above the penis. This is because there is simply no place to grab the penis from below because the balls are in the way (the penis does not protrude beyond the balls!) Most “normal-sized” guys don’t realize this. This applies to stretching and jelqing. Regarding the jelq, you have to hold the skin back with one hand and jelq with the other. You cannot do the two-handed method until you reach a certain size.
My routine is just stretching because I really want length and not girth for now. (Already 5.5 girth)
I have a theory about gains for the small penis. Because there is simply less tissue involved, there are fewer cells being broken down along the shaft during the stretch. This means that there are fewer cells being rebuilt/added/grown. However, as the penis gradually gets longer, with the same routine, there will be more and more cells being broken down and therefore more and more cells being created. So, my experience is that the rate of growth increases as the penis itself becomes bigger. This is why you hear of 7 inch guys adding an inch in 6 months but it took me two years to get an inch.
Patience & persistence.
Hope this helps.
