No gains in circumference

Hello everyone.

I’m from Belgium so sorry if you don’t understand me, i will try to be clear.

I have maintained my routine for 9 months but I only have gains in lengths. I got 2 cm BPEL and 0 cm EG.

My routine is 12 Minutes stretching and 20 minutes Jelqing.

I am very happy with my gains in length but I am disappointed for my gains in width, what can I do to have gains in both areas?

Thanks

Clamping
