Manuals without pumping.

I’m new to PE. I started recently by manual stretching. I don’t need girth, i need length only so i’ll only pull my dick out and down as what hink and BD preach.

I need an inch of length. That’s all for me.

But i have heard that manual stretching works when we combine pumping with it. I know pumping might enhance the gains, but can i still get that inch by only stretching?

I’m 5.7 bp with 5.1inch girth and am 20 years old (if that matters).

I’m starting with 30 minutes of manuals 6 days a week. I’ll do it regularly until i reach that 1 inch goal.

I need it so desperately.

So can i get that without including pumping?
