Pumping gains ?

Hey, I have never pumped but I am curious, and was thinking of trying it out to see what happens. What are the risks and what kind of size gains can I expect. From what have read the gains are temporary, and thats fine with me I just want to try it I think.

Nothing hurts in trying. Best advise if you don't get a pump with a gage is too not over do it. Your penis should stay pink/red during this whole process. If it turns purple you are doing it wrong.Many people have gained with pumping but it is over a long period of time. In the short term it is temporary. Get a gaged pump and don't go about 5hg.

Damn bro, just looked at your pix....do ya really think you need to?

(warning: I havent done it either, but I know it can sometimes misshape the dick in a funny lopsided way.)
