Does pumping bring length gains
I have been reading about pumping lately, I am in no hurry to get one yet but in the near future about 2-3 months from now I will love to own one. I have a couple questions, first of I read about air pumps and hydro pumps, I read somewhere hydro pumps are better, what are the differences between them?
I read it mostly help girth, but a lot of people here said it helps their length as well. On average how much of an increase in temporary gains do you get in length, I believe it can be up to two inches.
Thanks
